1General
1.1 Introduction
Power Supply Unit B10E is used to supply voltage to
the Circuit Breaker (CB) coils and spring-charging mo-
tor during installation and/or field service.
Since the high-quality voltage available at the coil
outputs is very load-independent, the power supplied
resembles what is encountered under normal oper-
ating conditions. Circuit breaker functionality thus
remains virtually unchanged.
B10E enables you to test CB functions easily at the
specified voltage levels.
1.2 Service and support
For technical assistance please contact your local
Megger representative or direct your request to the

2.2 Safety instructions
WARNING
1Always make certain that the DC system in the
substation is disconnected before connecting
B10E.
2Always ground the B10E.

OFF switch.
4Only connect B10E to an outlet protected with
max 16 A overcurrent protection
5High voltage/current on input/output terminals.
6Do not attempt to service the instrument your-
self. Opening or removing covers may expose
you to dangerous voltage. If you attempt to
service the instrument yourself the warranty is no
longer valid.
7Do not use any accessories that are not intended
for use together with the instrument.
8Disconnect the instrument from the mains before
cleaning. Use a damp cloth for cleaning. Do not
use liquid cleaners or aerosol cleaners.

2 SAFETY

IMPORTANT
1Always use safety connecting leads.
2Never leave the instrument unattended while it is
turned on.
3Use only approved mains detachable cable set
with the instrument. Main supply cables shall be
rated for the maximum current for the equip-
ment and the cable shall meet the requirements
of IEC 60227 or IEC 60245. Mains supply cables
certified or approved by a recognized testing au-
thority are regarded as meeting this requirement.
4Unplug the instrument from the mains supply
when it is left unattended or not in use.
5Refer all servicing to Megger authorized person-
nel.
6If you need to return the instrument, please use
either the original crate or one of equivalent
strength

4.1 Circuit breaker trigging
Important
Read the manual and comply with the
Safety instructions before using B10E.
Always comply with local safety regula-
tions.
When the master ON/OFF switch on B10E is turned
on, you are ready to proceed with testing. As a rule,
output is set for the coil outputs before B10E is
started. Moreover, the coil outputs are usually set for
DC and the trig input is set for voltage sensing.
Warning
If the coil current is below 50 mA the 1 sec
automatic interruption will not work. A
potential hazard for burning the trip coil.
Note The COIL DC and AC outputs, CLOSING/
BREAKING, cannot be used simultaneously. A
time limit is imposed on the DC outputs. If the
DC outputs are loaded with minimum 50 mA,
the current will be interrupted after about
one second to protect the automatic control
circuitry.
The AC outputs can be loaded for up to 30
minutes at maximum specified power.
1] Ground B10E.
2] Switch off the master ON/OFF switch.
3] Check that the substation voltage is discon-
nected from the circuits in which B10E is to
be connected.
4] Turn the variable transformer to zero.
5] Make connections to the CB operating cir-
cuits.
6] Connect B10E to the mains power.
7] Switch on B10E.
Note The current inrush on starting is high and can
trip/blow a 10 A fuse.
8] Select the desired trig function and output.
You can select either manual or external trig-
ging via the coil outputs.
For manual trig, set the trig input to voltage
sensing.
For external trigging, you can select either
zero-potential contact sensing or 8–15 V
voltage sensing. Since B10E is usually used
together with a circuit breaker analyzer,
external contact sensing is normally selected
and the trip input is normally provided with
a short-circuiting jumper
9] Set the voltage to desired level using the
variable transformer.
10] Operate the CB.
Note If any of the protective cut-outs on B10E trip,
a lamp marked PROTECTION will light up.
Reset by pressing the RESET button. However,
you must wait a while before the thermal cut-
out can be reset.
Application examples
Manual trigging of CB
1] Make certain that the mains are de-ener-
gized on both sides of the CB, and then
ground the CB on both sides.
2] Ground B10E.
3] Set the master ON/OFF switch on B10E to the
OFF position.
4] Connect the CB coil circuits to B10E, CLOS-
ING/BREAKING. Use the appropriate outputs
DC or AC. Connect the CB spring-charging
motor to B10E, MOTOR.
5] Connect B10E to the mains power.
6] Switch on the B10E master ON/OFF switch.
7] Check that B10E is set for the coil outputs,
and for the correct type of voltage, DC or AC.
8] Set the desired output voltage.
9] Select voltage sensing for the trig input.
10] Press the TRIG button (8) to start the desired
operation.

4 OPERATING INSTRUCTIONS

B10E together with a circuit breaker
analyzer
1] Make certain that the mains are de-ener-
gized on both sides of the CB, and then
ground the CB on both sides.
2] Ground B10E.
3] Set the B10E master ON/OFF switch to the
OFF position.
4] If the CB has a common negative terminal,
connect the positive side of CB operating
mechanism’s close and open circuits to the
circuit breaker analyzer outputs marked
CLOSE and OPEN. Connect the spring-charg-
ing motor’s positive and negative terminals
to the MOTOR outputs on B10E. Then con-
nect one of B10E’s COIL outputs, DC or AC,
to the negative input to the circuit breaker
analyzer (marked INPUT).
5] Connect B10E to the mains power.
6] Switch on the B10E master ON/OFF switch.
7] Check that B10E is set for the coil outputs
and for DC.
8] Select contact sensing for the trig input.
9] Check that the trig input is short-circuited.
10] Select the desired operation on the circuit
breaker analyzer’s sequencing unit and oper-
ate the CB from the circuit breaker analyzer.
