The 3AP1 power circuit breaker designed for high
voltages 145 for outside operations. The power
circuit breaker consists three insulator columns with
one operating unit each and shared control unit. Con
sequently, Han® HPR housings and seals have been cho
sen and have been specially developed withstand these
types stress. The
connections are pluggable order reduce assembly
work.
The relevant environmental conditions have taken
into account the circuit breaker can used outdoors. ensure secure and controlled
switching the high power, the three interrupters are
controlled electronically. Service and maintenance are simple procedures.
This connection realized using conductor special
cables transmit the sensor and actuator signals.

the drives and the control unit therefore essential. The pre-manufactured cables are tested before
shipping and thus minim ize the possibility iring er
