Masterpact™ MP circuit breaker
advantages
improved safety
•
segregated compartment
Once the front cover has been removed,
leaving access to the auxiliary compartment
the main contacts remain fully isolated.
Furthermore, interphase partitioning allows
full insulation between each pole even if the
front cover has been removed.
•
Isolation function
by
positive
indication of contact status
The mechanical indicator is truly
representative of all three main contacts
status.
•
reinforced insulation
Two insulation barriers separate the front of
the circuit breaker from main ciJ:Cuits.
•
disconnecting thru door
The racking handle and racking mechanism
are accessible through the front door cutout.
Disconnecting the breaker will be therefore
possible without opening the door and giving
access to live parts.
solid state protection and
control
Masterpactm is equipped with solid state
control units which provide all the traditional
protection of the universal power breaker
(long time, short time, instantaneous and
ground fault) plus other built-in functions :
