It's built for motor starter protection using a TM120M thermal-magnetic trip unit set for short-circuit protection only (no overload function), with an adjustable instantaneous trip range of 5 to 15 times In. The 125 A continuous rating matches a typical motor full-load current for a 75–90 kW motor, but since there's no overload protection built in, you'll need a separate overload relay upstream or in the starter. The shunt trip (STL) operates on 12–30 V DC or 24 V AC 50/60 Hz, letting you remotely trip the breaker from an E-stop or safety relay. ## Deployment context The nut keeper kit simplifies panel assembly — no dropped hardware when you're working in tight spots.","metaTitle":"3VA1112-6MH32-0HH0 Siemens 3VA1 IEC Frame 160 Breaker, 70kA","metaDescription":"Siemens 3VA1112-6MH32-0HH0 circuit breaker, IEC frame 160, 70kA @ 415V, 125A, shunt trip, aux switches.
