The Siemens SENTRON 3VA9467-0HC35 is a stored energy motor operator (SEO) with an integrated communication module, designed as a remote-controlled closing accessory for 3VA23 and 3VA24 molded-case circuit breakers. It is a motorized operating mechanism with a stored energy mechanism (SEO), meaning it charges a spring mechanism to close the breaker independently of the operator's speed or force — critical for applications requiring consistent closing time and remote or automatic reclosing. The control supply voltage range covers 110-230 V AC (at 60 Hz) and 110-250 V DC, with an operating apparent power of 300 VA. This wide-range supply makes it suitable for global panels where control voltage may vary between 110 V and 240 V AC or DC without needing a separate transformer tap. Typical make time is 0.08 s and break time is 5 s, which defines the closing speed and the discharge interval for the stored energy mechanism. The 0.08 s closing time ensures fast, repeatable breaker closure for coordination with upstream protective devices.
The 3VA9467-0HC35 mounts directly onto the 3VA23 or 3VA24 breaker frame. Physical dimensions are 159 mm depth, 137.6 mm width, and 127.4 mm height. The 159 mm depth is the key panel-dimension constraint — it extends behind the breaker face, so verify available enclosure depth before specifying. The 137.6 mm width matches the breaker width; no additional side clearance is needed beyond standard breaker spacing. The integrated communication module allows remote monitoring and control via the breaker's communication bus, eliminating the need for a separate interface module. This reduces wiring and panel space compared to a standalone motor operator plus separate comms gateway.
Rated for a maximum voltage of 250 V, which covers the control supply range. The stripped length for wiring connections is 7 mm.
