– relative humidity – 50 % at a temperature of plus 40 °Ñ, it is allowed to use
circuit breakers at a relative humidity of 90 % and a temperature of plus 20 °Ñ.
– non-explosive environment, not containing aggressive gases and vapors in
concentrations that destroy metals and insulation, not saturated with conductive
dust and water vapor;
Base product data
The circuit breaker complies with the requirements of Directive LVD
2014/35/EU, RoHS 2011/65/EU, IEC 60947-2, IEC 60947-7-3.
The circuit breaker can be operated under the following conditions:
– operating temperature range from minus 40 °Ñ to plus 60 °Ñ;
– environment condition group according to IEC 60947-1 – A, B*;
– utilization category according to IEC 60947-2 – À (not intended to provide
selectivity);
(hereinafter referred to as circuit breaker) is designed to conduct
current in normal mode and turn off overcurrents in case of short circuits and
overloads, as well as for infrequent (up to 30 times a day) operational switching
on and off of electrical circuits in three-phase alternating current electrical
networks with voltage up to 690 V and 50 Hz.

The circuit breaker is installed on a metal panel with a thickness of at least
1.5 mm or an insulating panel with a thickness of at least 6 mm and fixed with the
screws included in the delivery.
The time-current characteristics of the switch are shown in figure 5.
Setting temperature of the release – plus 40 °C. The technical parameters of
the circuit breakers, depending on the type, are given in table 2. Figure 1 shows the
graph of the dependence of the rated current value on the ambient temperature.
The thermal release operates with an inverse time delay and must open the
circuit breaker with an error of ±10 % from operating current value of the IR
thermal release setting in accordance with table 3.
For the switch, you can additionally purchase extended terminals and
adapter tips. The dimensions of the extended terminals and adapter tips for the
V88 are shown in figure 3. The adapter tips are designated as, "For the central
terminal" and represent three straight copper busbars. The extended terminals
consist of one central and two side buses.
Completeness
The connection of the corresponding flexible conductors or busbars is
carried out using the fasteners for connecting the external conductors.
Installation rules
The releases are adjusted and calibrated at the factory and are not
accessible during operation.

The circuit breaker allows voltage supply from the power source both from
the side of terminals 1, 3, 5 and from the side of terminals 2, 4, 6.
The circuit breaker is a repairable product. It is necessary to periodically
(at least once a year) check the tightness of the connection screws. After each
disconnection of the short-circuit current, it is necessary to inspect the circuit
breaker and, in addition, it is recommended to perform the "on-off" operation
8–10 times without current, then simulate the automatic operation of the circuit
breaker by pressing the "Test" button.
In case of circuit breaker failure or failure detection, contact the
organizations specified below.
Connection of both copper and aluminum conductors is allowed. It is
recommended to use lugs together with flexible conductors (not included in the
delivery set). The dimensions of the connected lugs and busbars should
correspond to those presented in figures 5, 6, 7 and tables 6, 7, 9. The size of the
core to be crimped (crimped) with the help of the lug should be selected taking
into account the requirements of BCH 13983.
The normal operating position of the circuit breaker in space is on a vertical
plane with terminals 1, 3, 5 upwards; installation on a vertical plane with the
rotation of terminals 1, 3, 5 to the left or right by 90° is allowed.
The circuit breaker should not be disposed as household waste. For
disposal, transfer to a specialized recycling company.
Basic insulation is a precautionary measure for basic protection against
electric shock, and no protection against damage is provided.
Transportation of the circuit breaker is allowed by any kind of covered
transport in the manufacturer's package, which protects the packed circuit
breaker from mechanical damages, pollution and moisture ingress at
temperatures from minus 40 °C to plus 60 °C.
The control handle of the circuit breaker has three positions: "ON", "OFF",
middle position. At the first turn-on and after the protective shutdown (including
when the shunt and undervoltage release trips), to close the main contact group
of the circuit-breaker, it is necessary to move the handle from the middle position,
first to the "OFF" position, then to the "ON" position.
At the end of its service life, the circuit breaker should be disposed of.
The circuit breaker design contains an in-service inspection device – the
"Test" button, when pressing, the main contact group is reset (in this case, the
control handle of the circuit breaker will take the middle position).
Transportation, storage and disposal
The interphase baffles included in the delivery set should be installed in the
corresponding grooves during the installation of external conductors.
Storage of the circuit breaker is carried out in the manufacturer's package in
rooms with natural ventilation at an ambient temperature of from –40 °C to +60 °C
and relative humidity up to 50 % at a temperature of +40 °C, it is allowed to store
the circuit breaker at a relative humidity of 90 % and a temperature of plus 20 °C.

Service life and manufacturer's warranty
The circuit breaker that has worked the total number of on-off cycles
provided for by the technical conditions before the expiration of the warranty
cannot be replaced or repaired.
The warranty period for the circuit breaker is 5 years from the date of sale,
provided that the consumer observes the rules for installation, operation,
transportation and storage.
Claims for the circuit breaker will not be accepted in the event of damage of
the protection of the factory settings of the thermal release or an independent
change in the design of the product by the consumer.
The service life of the circuit breaker is 15 years.
