Device description

Door-Coupling Rotary Handle

Door-coupled rotary operating handle mechanically linked to a device installed inside an enclosure.

A door-coupling rotary handle allows a breaker or disconnector to be operated from outside a closed enclosure door.

The mechanical connection between the handle and the device is normally provided by an extension shaft or a dedicated coupling mechanism.

Correct installation depends critically on the minimum and maximum device-to-door distance because this defines the usable coupling range.

Selection criteria include device compatibility, cabinet depth range, shaft type, IP degree of protection, locking capability and mounting position.
