It provides remote switching capability for these breakers, drawing 250 VA apparent power at its control input. Control voltage range spans 24 to 60 V DC, covering common industrial control voltages from 24 VDC PLC outputs up to 48 VDC and 60 VDC panel supplies. The mechanism's make and break time is rated at 1 s typical, giving a predictable switching sequence for coordination with downstream contactors or motor starters. Mounting footprint is 105 mm wide × 75 mm tall × 132 mm deep. The 132 mm depth is the critical dimension for enclosure depth — verify the panel door clearance allows the mechanism to operate through its full stroke without interference from wiring ducts or busbars. Terminal wiring accepts conductors with a stripped length of 7 mm, matching standard ferrule lengths for control wiring in panel builds. ## Environmental range and lifecycle The -40 °C low end suits cold storage or northern installations; the 80 °C upper limit accommodates heat rise inside a sealed panel near the breaker.","metaTitle":"Siemens 3VA9277-0HA10 SENTRON Motor Operator, 24-60V DC, for","metaDescription":"Siemens SENTRON 3VA9277-0HA10 motorized operating mechanism (MO) for 3VA6 150/250 and 3VA5 250 breakers. 24-60V DC, 250 VA.
