This Siemens 3VA9447-0HC10 is a stored energy motor operator, functioning as an accessory for the 3VA63 and 3VA64 series circuit breakers. It requires a 24V DC control supply voltage and offers a rated operational power of 300 VA.
The device features a typical make time of 0.08 seconds and a break time of 5 seconds. Its mechanical dimensions are 127.4 mm in height, 137.6 mm in width, and 159 mm in depth, with a net weight of 1980 g. The operator supports conductor cross-sections ranging from 1.5 mm² to 2.5 mm² for solid, finely stranded (with core end processing), and stranded conductors.
Operating temperature ranges from -25 °C to 70 °C, while storage temperature can be between -40 °C and 80 °C. The tightening torque for connections is specified between 0.36 N·m and 0.44 N·m, with a required stripped length of 7 mm for connections according to IEC standards.
