The TM240 thermal-magnetic trip unit provides overload protection adjustable from 88 A to 125 A and short-circuit pickup from 5 to 10 times In. A built-in shunt trip (STL) operates on 220–250 V DC or 208–277 V AC, allowing remote tripping from a safety circuit or emergency-stop chain. The nut keeper kit secures the breaker in the panel against vibration in high-shock environments.","metaTitle":"Siemens 3VA1112-5EF32-0KA0 Circuit Breaker, 55kA @ 415V, 125","metaDescription":"Siemens 3VA1112-5EF32-0KA0 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 125A TM240 thermal-magnetic trip, shunt trip 220-250VDC/208-277VAC.
