The Extended Rotary Handle (ERH) has extended rotary handle mechanisms to mount on front of an enclosure door and operate externally. A new safety feature allows the external handle to quickly show the state of the circuit breaker without opening the panel and a new, larger handle design gives the user more leverage than previous models. The Flange Handle Mechanism (FHM) mounts on the flange of an enclosure door, occupying less space inside the enclosure. It is designed to allow the handle to be mounted anywhere on the panel or next to it. Both are available for M1/M2/M3/M4 MCCBs.
