Rotary handle operating mechanism
This is an operating device that allows the circuit-breaker to be operated by means of a rotary handle,
which makes the circuit-breaker easier to open and close thanks to its ergonomic handgrip.
Different types of handles are available:
• direct (RHD): installed on the front of the circuit-breaker for frontal operation;
• transmitted (RHE): installed on the panel door. It allows the circuit-breaker to be operated by means
of a rod which acts on a base installed on the front of the circuit-breaker; also an heavy duty version
called RHE_MB is available;
• lateral (RHS): installed directly on the front of the circuit-breaker for side operations.
For XT1, XT2, XT3 and XT4 a large handle grip (LH) is also available, which can be combined with the
transmitted handle (RHE) and with the lateral handle (RHS).
