The 3AP1 power circuit breaker designed for high

insulator columns each contain interrupter unit and
the necessary drives. ensure secure and controlled
switching the high power, the three interrupters are
controlled electronically. Even snow and ice can not excluded.
The relevant environmental conditions have taken
into account the circuit breaker can used outdoors. The pre-manufactured cables are tested before
shipping and thus minim ize the possibility iring er

circuit breaker consists three insulator columns with
one operating unit each and shared control unit.
Temperature fluctuations and humidity particular play
a key role
