The 63 A thermal-magnetic trip (TM120M) provides short-circuit protection adjustable from 5 to 15 x In, but note the description explicitly states it ships without overload protection, so this unit is intended for applications where overload protection is handled upstream or by a separate motor starter relay. ## Integrated control and signalling Factory-fitted with a shunt trip (STL) rated 12–30 V DC and 24 V AC 50/60 Hz, plus two HQ auxiliary switches and one HQ trip alarm switch.","metaTitle":"Siemens 3VA1163-6MH32-0HH0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH32-0HH0 IEC frame 160 MCCB, 70kA breaking capacity at 415V, 63A, shunt trip 12-30V DC, 2 aux switches.
