The Siemens 3VA9267-0HA22 is a motorized operating mechanism (MO) from the SENTRON accessory line, designed to remotely open and close 3VA2 molded case circuit breakers in the 100 A, 160 A, and 250 A frame sizes. It's the part that lets a PLC or remote pushbutton turn the breaker on and off without someone standing at the panel door. Rated control supply voltage is 230 V AC at 60 Hz, pulling an operating apparent power of 250 VA. Make and break times are both 1 s — that's the full stroke time, not a trip curve. It's optimized for long control cables, which matters when the breaker is in a remote MCC or a separate switchroom.
Mounting dimensions: 105 mm wide, 75 mm tall, 132 mm deep. The depth includes the mechanism body and any rear projection — check clearance behind the panel door before committing. Stripped length for the control wires is 7 mm, standard for the screw-clamp terminals on this accessory. No IP rating is listed on this accessory — it relies on the breaker enclosure it mounts to for ingress protection.
