It's a SENTRON-series accessory for 3VA63 and 3VA64 breakers, enabling remote electrical closing. Rated for 24 V DC control, the mechanism draws up to 300 VA during the charge cycle. The make time is a consistent 0.08 s — that's the spring discharging to close the breaker contacts. Break time runs 5 s, which is the motor re-charging the spring after a close operation. Mounts directly onto the breaker frame — no separate DIN-rail footprint. The accessory adds 159 mm depth and 137.6 mm width to the breaker assembly, so verify enclosure depth clearance if retrofitting into an existing panel. Terminal strip accepts 7 mm stripped wire. The DC control circuit needs a 24 V supply capable of the 300 VA inrush during the charge cycle; a dedicated power supply or transformer is typical.","metaTitle":"Siemens 3VA9447-0HC10 SENTRON Stored Energy Motor Operator,","metaDescription":"Siemens 3VA9447-0HC10 SENTRON stored energy motor operator (SEO) for 3VA63/3VA64 breakers. 24V DC, 300 VA, 0.08s make time.
