The Siemens SENTRON 3VA9267-0HA20 motorized operating mechanism (MO) for 3VA2 breakers in 100/160/250 A frames. Accepts 110–230 V AC or 110–250 V DC control supply, 250 VA apparent power, 1 s make/break times.
What the ratings mean for fit
Control voltage range 110–230 V AC or 110–250 V DC, 250 VA apparent power during 1 s closing pulse. Ambient –40 to +80 °C, stripped length 7 mm.
Where it goes
This motor operator mounts directly onto the front of a 3VA2 breaker and replaces the standard rotary handle. It is designed for panels requiring remote open/close control — typical in generator automatic transfer schemes, solar combiner boxes, or process skids where the breaker must be cycled from a PLC or SCADA system. The stripped length of 7 mm indicates the wire termination needs for the control wiring.
