Siemens 3VA9467-0HA20 SENTRON Motorized Operating Mechanism 110-230 V AC / 110-250 V DC

The Siemens 3VA9467-0HA20 is a robust motorized operating mechanism designed to automate switching for SENTRON 3VA1 and 3VA2 molded case circuit breaker series rated up to 400/630 A. This accessory enables remote or automatic operation of heavy-duty circuit breakers, supporting control voltages from 110 V to 230 V AC and 110 V to 250 V DC, making it versatile for integration in industrial and commercial power distribution systems.

Built to reliable Siemens standards, this MO (motor operator) accessory provides typical make and break times of ~1.7 s and ~1.3 s respectively, helping streamline electrical operations and improve safety during automated switching. It’s engineered with sturdy connections and compatible conductor sizes from 1.5 mm² to 2.5 mm², and its compact form factor is suitable for retrofits or new installations in control panels.

The 3VA9467-0HA20 enhances the flexibility of SENTRON 3VA molded case circuit breakers by enabling remote control via external signal systems, PLCs, or building management systems — ideal for automated load shedding, fault interruption routines, and centralized power control architectures.
