Side Rotary Handles

Side-Mounted Rotary Handle


The side-mounted rotary handle is compatible with 3- and 4-pole unit-mount circuit breakers.

The side-mounted rotary handle kit is made up of:

  • a rotary mechanism that has to be mounted to the front accessory cover of the circuit breaker using three screws.

  • an assembly (handle and nut) that mounts on the side (left or right) of the enclosure.

  • a cut-to-length extension shaft.

The handle assembly is fixed with a nut (Ø 22 mm) to make assembly easier.

The side-mounted rotary handle makes it possible to operate a circuit breaker installed in an enclosure from the side. The side mounted rotary handle maintains:

  • suitability for isolation.

  • indication of the three positions OFF (O), ON (I) and tripped (Trip) is visible on the handle (outside the panel) and on the rotary mechanism (inside the panel).

  • visibility of and access to the trip unit when the door is open.

  • degree of protection of the handle on the side: IP54 or IP65 as per IEC 529.

Device Padlocking

Padlocking Side-Mounted Rotary Handle

The handle may be locked in the OFF position using 1 to 3 padlocks diameter Ø 4–8 mm (3/16–5/16 in.). Padlocks are not supplied.

The black handle can be modified during installation to allow locking in the ON and OFF positions. Locking in the ON position does not prevent the circuit breaker from tripping if an overload or short circuit condition occurs. In this case, the handle remains in the ON position after the circuit breaker trips. Unlocking is required for the handle to go to the tripped position then the OFF position to reset the circuit breaker.

Shaft Length

The shaft length is calculated using the distance between the nearest side of the circuit breaker and the side of the enclosure:

  • Minimum shaft length is 45 mm (1.77 in.).

  • Maximum shaft length is 480 mm (18.90 in.).

  • Shaft length must be adjusted to the particular installation.


  • Standard with black handle (IP54).

  • VDE type with red handle and yellow bezel for machine tool control (IP54).

  • Standard with an IP65 universal handle (red handle and yellow bezel).

IP54 models are suitable for mounting on the flat surface of enclosures rated Type 12. IP65 models are suitable for use in Type 12, 3R and/or 4X enclosure applications.


The side-mounted rotary operating handle is UL Listed under file E103955 and CSA Certified under file 177007.
