Accessory for 3VT circuit-breakers — Interlock between rotary mechanism and compartment door
Safety Instructions
Read and understand these instructions before installing,
operating, or maintaining the equipment.
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working on equipment.
CAUTION
Reliable functioning of the equipment is only ensured with
certified components.
The status indications ("ON", "TRIPPED", "OFF") of the circuit-
breaker and the "RESET" position are indicated on both the
operating panel as well as on the rotary handle.
All rotary operating mechanisms can be locked in the OFF posi-

equipped with rotary operating mechanisms may be used as
main devices. Rotary operating mechanisms can be interlocked
with the switchgear cabinet door to avoid opening the door when
the circuit-breaker is closed.
