Undervoltage Release Trips the circuit-breaker when
the voltage is interrupted. Prevents the motor from being restarted accidentally when the
voltage is restored, suitable for
EMERGENCY STOP acc. to
VDE 0113
Shunt Release Trips the circuit-breaker when
the release coil energized.

Enclosure Plastic enclose with rotary operating mechanism, lockable space for aux. contact + release J77MN-PF-3R
Enclose with rotary operating mechanism yellow - red, lock space for aux. contact + release J77MN-PFC-3R
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.
Link modules Mechanical and electrical connection between Motor Pro-
tection Circuit Breaker and Contactor. Up-to max. 32 A.
