It ships with a TM120M thermal-magnetic trip unit set for starter protection (motor branch circuit), adjustable short-circuit pickup Ii = 5–15 × In, and no integral overload relay — the motor's own overload block handles that. ## What the integrated accessories mean for your panel This breaker comes factory-fitted with a shunt trip (STL) rated 220–250 V DC / 208–277 V AC and two HQ auxiliary switches. The shunt trip lets a remote safety relay or PLC cut power independent of the handle — useful for emergency-stop circuits or interlocked guards. A nut keeper kit is also included, which simplifies DIN-rail or mounting-plate installation by holding the hardware captive during assembly.","metaTitle":"Siemens 3VA1112-6MH32-0KC0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH32-0KC0 IEC frame 160 MCCB, 3-pole, 125A, breaking capacity class H Icu=70kA @ 415V AC.
