This variant ships without overload or short-circuit protection — it is a pure disconnect, not a circuit breaker. The integrated shunt trip (STL) coil, rated 110–127 V DC/AC 50/60 Hz, allows remote or emergency-off tripping. Dimensions are 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB footprint that drops into standard DIN-rail or panel-mount enclosures. Main circuit connections are busbar-type front terminals, which keep wiring organized in multi-feeder panels. A motor-drive option is available as an accessory (field-installable), enabling remote motorized operation for automated disconnection sequences.","metaTitle":"Siemens 3VA1110-1AA42-0JC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA42-0JC0 switch disconnector, 100 A rated current, 4-pole, 690 V AC, with shunt trip STL and 2 HQ auxiliary switches.
