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
office in Sweden.

substation is disconnected before connecting
B10E.
2Always ground the B10E.
3Before connecting B10E, turn off its master ON/
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service the instrument yourself the warranty is no
longer valid.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
