I. Introduction
This publication contains the information needed to install medium voltage eVM1 (withdrawable
version for UniGear ZS1 type switchgear and PowerCube modules) and put them into service.
For correct use of the product, please read it carefully.
Like all the apparatus we manufacture, the eVM1 circuit-breakers are designed for different instal-
lation configurations.
However, they do allow further technical and construction modifications (at the customer’s re-
quest) to adapt to special installation requirements.
For this reason, the information given below may sometimes not contain instructions concerning
special configurations.
Apart from this manual, it is therefore always necessary to consult the latest technical documen-
tation (circuit and wiring diagrams, assembly and installation drawings, any protection coordina-
tion studies, etc.), especially regarding any variants requested in relation to the standardised
configurations.
Only use original spare parts for maintenance operations.
For further information, please also see the technical catalogue of the circuit-breaker.
All the installation, putting into service, running and maintenance operations must be car-
ried out by skilled personnel with in-depth knowledge of the apparatus.
II. Environmental protection programme
The eVM1 circuit-breakers are manufactured in accordance with the ISO 14000 Standards (Guide-
lines for environmental management).
The production processes are carried out in compliance with the Standards for environmental
protection in terms of reduction in energy consumption as well as in raw materials and production
of waste materials. All this is thanks to the medium voltage apparatus manufacturing facility envi-
ronmental management system.

3. Storage
When a period of storage is foreseen, our workshops can (on request) provide suitable packing
for the specified storage conditions.
On receipt the apparatus must be carefully unpacked and checked as described in Checking on
receipt (chap. 2).
If immediate installation is not possible, the packing must be replaced, using the original material
supplied.
Insert special hygroscopic substances inside the packing, using at least one standard packet per
piece of apparatus.
Should the original packing not be available and immediate installation is not possible, store in a
covered, well-ventilated, dry, dust-free, non-corrosive ambient, away from any flammable materi-
als and at a temperature between –5 °C and +45 °C.
In any case, avoid any accidental impacts or positioning which stresses the structure of the appa-
ratus.
4. Handling
Before carrying out any operations, always make sure that the capacitors are discharged.
To lift and handle the circuit-breaker, proceed as follows (fig. 2):
– use a special lifting tool (1) (not supplied) fitted with ropes with safety hooks (2);
– insert the hooks (2) in the supports (3) fixed to the frame of the circuit-breaker and lift. Latch the
hooks (2) into the support holes (3) according to the type of apparatus (see table);
– on completion of the operation (and in any case before putting into service) unhook the lifting
tool (1) and dismantle the supports (3) from the frame.
During handling, take great care not to stress the insulating parts and the terminals of the circuit-
breaker.

5. Description
The eVM1/P type vacuum circuit-breakers are designed for indoor installation in air-insulated
switchgear.
In respect of the technical characteristics, eVM1/P circuit-breakers are suitable for operation of
electric circuits under normal and fault service conditions.
The vacuum circuit-breakers have particular advantages when used in systems with a high fre-
quency of operations and/or which lead to a certain number of short-circuit trips.
The eVM1/P type vacuum circuit-breakers stand out for their particularly high operating reliability,
extremely long useful life expectancy and for being completely maintenance-free.
The eVM1/P type vacuum circuit-breakers are available in the withdrawable version. Their basic
structure is shown in the “Technical data” section.
5.1. Standards and regulations
5.1.1. Fabrication
The eVM1 circuit-breakers conform to the following Standards:
• VDE 0670, part 1000, and IEC 60694
• DIN VDE 0670, part 104, and IEC 62271-100
• DIN VDE 0847, part 4, and IEC 61000-4.
The apparatus must not be handled by putting lifting devices directly under the apparatus
itself. Should it be necessary to use this technique, put the circuit-breaker onto a pallet or
a sturdy supporting surface (see fig. 3).
In any case, it is always advisable to carry out lifting using the supports (3). Hole “D” must
never be used.

6. Structure
6.1. Drive structure
The drive is of the magnetic type and basically consists of the magnetic actuator (8) (fig. 4), the
control module (10), the current sensors (3), the capacitor/s (2) and the kinematics which transmit
the movement to the circuit-breaker poles.
The actuator (8) acts on the circuit-breaker poles by means of special kinematics. The capacitor/
s (2) provides/provide the energy required for the operation.
The mechanical operating positions of the circuit-breaker are detected by two due sensors (14).
The basic version of the circuit-breaker is fitted with the following controls and instruments:
• coupling for manual emergency operation (9)
• mechanical state indicator (6)
• mechanical operation counter (5)
• control panel (7) with opening and closing pushbuttons.
6.1.1. Structure of the control module
The control module (10) of the circuit-breaker consists of:
• a microprocessor
• opto-electrical input couplers
• output relay
• electronic power system for controlling the actuator coils.

6.1.2. Capacitor
The energy for operating the circuit-breaker is stored in one or two capacitors according to the
circuit-breaker model (fig. 5).
The capacitors are designed so that the energy for an O-C-O operating cycle is supplied without
the need for recharging.
The energy stored by the capacitor is constantly monitored by means of measuring the relevant
voltage.
The “UNIT READY” indication signals application of the power supply voltage and the “ready” state
of the circuit-breaker for the next operation.
The energy stored in the capacitors determines the position of the READY/NOT READY contacts
and lighting up of the luminous “UNIT READY” signal according to the following criteria:
• Case 1: circuit-breaker in the open position.
- The energy available is sufficient for one closing and opening operation.
• Case 2: circuit-breaker in the closed position.
- The energy available is sufficient for one opening operation.
- The energy available is sufficient for one opening operation within about 30 seconds from
interruption of the auxiliary power supply.
If the energy stored is not sufficient, the luminous “UNIT READY” signal is off, the “READY” contact
is open and the “NOT READY” contact is closed to indicate that the circuit-breaker is not ready for
the operation.
6.1.3. Position sensors
The use of two inductive position sensors (fig. 6) allows the state of the circuit-breaker (open -
closed - anomalous intermediate position) to be determined without the use of auxiliary contacts,
allowing continual monitoring of the system.

6.2. Structure of the circuit-breaker poles
The poles are installed in the rear part of the circuit-breaker frame (fig. 7).
The active parts of the poles (vacuum interrupters) are embedded in epoxy resin and protected
against shocks and other external agents.
With the circuit-breaker closed, the current flows from the top terminal (1) to the fixed contact (1a)
in the vacuum interrupter (4), and then through the moving contact (2a) and the flexible connector
(6) as far as the bottom terminal of the circuit-breaker (2).
The movement of the moving contact are ensured by the insulating tie-rod (8) and by the kinemat-
ics (9).

6.3. Basic structure of the withdrawable circuit-breaker
The withdrawable truck (4) (fig. 8), either manual or motorised, consists of a steel sheet structure
with wheels (3), on which the circuit-breaker with the relative auxiliary components, the isolating
contacts (2) for electrical connection with the switchgear and the multi-pole connector (1) for
connection of the circuit-breaker auxiliary circuits are installed.
After having been racked into the switchgear and hooked up, the withdrawable circuit-breaker
can take up the following positions: racked-out, isolated for test (with connector inserted) and
racked-in. The racked-in circuit-breaker is automatically earthed by means of the truck wheels.
The magnetic actuator of the circuit-breaker and the relative controls and indicators, are accessi-
ble from the front.
Withdrawable circuit-breakers of the same type and characteristics are interchangeable. How-
ever, the code of the connector prevents incorrect combinations between the circuit-breaker and
switchgear.
7. Operation
7.1. Operation of the circuit-breaker drive
7.1.1. Magnetic actuator
The magnetic actuator used in the eVM1 circuit-breakers generates the run required to operate
the moving contacts of the interrupters and integrates all the functions of a traditional operating
mechanism.
The magnetic actuator is a bistable system where end-of-run positions of the moving armature
are reached by means of magnetic fields generated by two coils (one for closing and one for
opening).
The moving armature is kept in position by permanent magnets.
The circuit-breaker operations are obtained by means of energisation of the opening or closing
coil respectively. The magnetic field generated by each coil attracts the moving armature and
thereby moves it from one of the latching points of the permanent magnets to the other.

13
The capacitors which allow circuit-breaker operation, for a maximum time of about 30 seconds (with
closed circuit-breaker), even in the case of a drop in the auxiliary voltage, are provided in the control
circuit. In case of emergency, the circuit-breaker can in any case be opened by means of a special
crank handle which acts directly on the moving armature of the drive.
Compared to a traditional operating mechanism, the magnetic actuator has few moving parts and
greatly reduced wear even after a high number of closing and opening cycles.
These characteristics therefore make it practically maintenance-free.
7.1.2. Opening and closing operations
The opening and closing operations can either be remotely controlled by means of the special
inputs provided in the control module, or locally by pressing the pushbuttons on the control panel (7)
(fig. 4).
During the operations, the moving armature of the actuator acts directly on the moving contact by
means of the kinematics (8-9-10) (fig. 7).
7.1.3. Reclosing function
Thanks to the short duration of capacitor recharging, the drive is suitable for multiple reclosing
operations with O-0.3s-CO-15s-CO cycle.
7.1.4. Control module functions
All the conditions for controlling the opening and closing commands given to the magnetic actua-
tor are managed by a microprocessor:
• The power supply voltage must be applied to the AC/DC converter.
• The capacitor must be sufficiently charged for the next operation:
Circuit-breaker position Operations
Open Closes and Opens
Closed Opens
Magnetic latching in end-of-run position.
Magnetic latching and action of the magnetic field of a coil.
Moving armature in opposing position and magnetic end-of-run latching.
• The closing coil can only be activated when the circuit-breaker is open
• The opening coil can only be activated when the circuit-breaker is closed
• Closing is disabled when an opening command is active at the same time
• De-activation of the opening or closing coil takes place when the relative limit position has been
reached.
• WRONG POSITION (auto trip) function: if the final CLOSED (or OPEN) position is not reached
within 70 ms during a closing (or opening) operation, an opening operation is immediately started
to guarantee reaching a defined safe position in any case.
• The anti-pumping function ensures that only one closing-opening cycle is carried out when a
closing command followed by an opening command is active. The active closing command must
be cancelled and reset for the next closing operation.
• Activation of the input for the closing command can be locked by means of an external locking
signal.
• The input for the “lock on closing” command must be energised to be able to close the circuit-
breaker (without power it inhibits closing).

tion.

Fig. 9
• Undervoltage function: controls circuit-breaker opening if the applied voltage drops below the
tolerance limit (established by the Standards).
To prevent the function intervening when the voltage drops below the specified level (e.g. in the
case of motor starting), it is possible to set a trip time.
The undervoltage function is normally disabled. In this case, it is possible to open and close the
circuit-breaker without applying voltage to the input of the function.
• Monitoring function of the actuator closing and opening coil. This function serves to monitor the
continuity of the closing and opening coils of the magnetic actuator to detect any faults.
If a fault is detected, the luminous “COILS OK” signal on front of the circuit-breaker turns off and
the “READY/NOT READY” signalling contacts are commutated.
• Additional safety opening command function. The second input of the control module for the
opening function is designed so that an opening command is carried out directly even in the case
of a fault in the microprocessor.
7.1.5. Truck locking magnet
The locking magnet is inserted in withdrawable circuit-breakers with manual movement and pre-
vents traverse of the withdrawable truck when there is no power supply voltage. It is also linked to
the interlock between circuit-breaker closed and truck: it guarantees that even in a situation with
main welded contacts, the circuit-breaker cannot be isolated.
7.2. Principle of extinction of the vacuum interrupter
Given the relatively low static pressure of the interruption chamber (between 10-4 and 10-8 hPa), a
relatively limited distance between the contacts is required to obtain high dielectric strength. The
vacuum arc is extinguished on the first passage of the current through natural zero.
Considering the limited distance between the contacts, the high conductivity of the plasma of
metallic vapours, the drop in voltage of the arc and, moreover, the short arcing time, the energy
associated with the arc is extremely limited, therefore producing benefits for the useful life of the
contacts obtained and, consequently, for the useful life of the vacuum interrupters.

7.3. Interlocks
7.3.1. Interlocks / protection against malfunction (for withdrawable circuit-breakers for UniGear
ZS1 type switchgear and PowerCube modules)
A series of interlocks is provided to prevent incorrect operations and/or malfunctions. The inter-
locks are the following:
• the withdrawable truck can only be moved from the test/isolated position to the service position
(and vice versa) if the circuit-breaker is open (this means that first of all the circuit-breaker must
be opened).
• the circuit-breaker can be closed if the withdrawable truck is exactly in the defined test position
or in the service position (electric interlock).
• the circuit-breaker can be opened manually in the service or test position when it is not pow-
ered, but it cannot be closed.
• the switchgear is provided with devices which only allow connection and disconnection of the
plug connector (1) (fig. 10) in the test/isolation position.
Any detailed information regarding additional interlocks, e.g. with the earthing switch operating
mechanism, is given in the specific order documentation.
7.3.2. Interlocks in the case where withdrawable trucks are used UniGear ZS1 type switch-
gear and PowerCube modules
1) There is the possibility of configuring a binary input and relative function to allow the lock on
circuit-breaker closing when a voltage of 24 V - 240 V a.c./d.c. is applied to the input (electric
closing lock).
2) The eVM1/P circuit-breaker can only be closed when the withdrawable truck is in the test or
service position. In intermediate positions the closing lock voltage is cut off by the auxiliary
contacts of the truck.
3) A mechanical interlock positioned on the withdrawable truck prevents a closed circuit-breaker
being moved from the test position to the service position.
