The Siemens 3VA9467-0HC10 is a stored energy motor operator (SEO) — a motorized operating mechanism for SENTRON 3VA molded-case circuit breakers. It mounts on the breaker and provides remote electrical charging of the spring mechanism, so the breaker can be closed or opened from a PLC or pushbutton without an operator at the handle. Rated for 24 V DC control voltage, it draws 300 VA during the spring-charging cycle. The make time is 0.08 s and the break time is 5 s — the fast make ensures the contacts close cleanly, while the longer break time reflects the mechanical discharge of the stored-energy spring.
This SEO is designed specifically for the 3VA13, 3VA14, 3VA23, and 3VA24 frame sizes. It bolts onto the breaker's front cover and connects to the control circuit via the terminal block. The 159 mm depth, 137.6 mm width, and 127.4 mm height mean it adds about 160 mm to the breaker's overall depth — account for that in the panel layout if retrofitting an existing enclosure. The stripped length of 7 mm on the control wiring terminals is standard for spring-cage or screw terminals on this class of accessory.
