The Siemens 3VA9467-0HC15 is a stored energy motor operator (SEO) with an integrated communication module, designed as an accessory for SENTRON 3VA13, 3VA14, 3VA23, and 3VA24 molded-case circuit breakers. It provides remote electrical charging of the breaker's spring mechanism, enabling automated reclosing or remote switching without an operator at the panel. Rated for 24 V DC control voltage with a 300 VA operating apparent power draw, this SEO stores energy in its spring mechanism and releases it on command, giving a typical make time of 0.08 s and a break time of 5 s. That 300 VA inrush is the peak the control transformer or DC supply sees during the spring-charging cycle — size your 24 V DC supply for that momentary load, not the steady-state holding current.
The 3VA9467-0HC15 mounts directly onto the front of the compatible 3VA breaker frame — it is not a DIN-rail component but a bolt-on accessory that becomes part of the breaker assembly. Overall dimensions are 137.6 mm wide by 127.4 mm tall by 159 mm deep, so it adds that depth to the breaker's existing projection inside the enclosure. Panel builders should account for the additional 159 mm behind the door when laying out gland plates and busbar clearance. The integrated communication module means one less separate device to wire and mount in the panel — the SEO handles both the motor operator function and the control interface in a single package. Stripped length for the control wiring terminations is 7 mm, standard for spring-cage or screw terminals on this class of accessory.
Environmental range and approvals
The wide span means it is a candidate for outdoor enclosures in temperate climates, though the breaker's own rating and enclosure IP class will set the final limit.
