Door-coupling rotary
The door-coupling rotary operating mechanisms consist of
a knob, a coupling driver and an extension shaft (5 mm x
5 mm, lenght 330 mm). The door-coupling rotary operating
mechanisms are designed for degree of protection IP 65.
The door locking device prevents accidental opening of the
cubicle door in the ON position of the circuit-breaker. The
OFF position can be locked with up to 3 padlocks.
