Siemens 3VF9623-1MC20 is a motorized operating mechanism (MOM) designed as an accessory for the 3VF6 molded‑case circuit breaker in L‑frame configurations. This rotary drive provides remote, automated actuation of the 3VF6 and operates from a 60 V DC supply, without a locking device. It is described as the rotary drive accessory for 3VF6 breakers, intended for installation in the door or cover area with a red knob and no auxiliary switch, making it suitable for panel enclosures and other switchgear that require motorized operation. The 3VF9623‑1MC20 is specifically compatible with the 3VF6 family of circuit breakers and is marketed as an accessory rather than a standalone device.
