17 Mechanical door interlock
This device prevents the circuit-breaker from being
racked in when the switchgear door is open. It can
only be used for circuit-breakers installed in UniGear
ZS1 switchgear and PowerCube modules equipped
with the relative actuator on the door.
18 Motor-operated truck (-MAT)
Allows the circuit-breaker to be racked in and out of
the switchgear by remote control (only for circuit-
breakers in the withdrawable version for UniGear
ZS1 and ZS8.4 switchgear and PowerCube modules).
The motor-operated version with clutch can be
ordered on request, so that racking-in/out can be
performed in an emergency if the truck motor fails
to operate.
