The TM120M thermal-magnetic trip unit provides fixed thermal protection (the 'TM' part) and adjustable magnetic pickup from 5 to 15 times In, so you set the short-circuit threshold to match the inrush of your motor or transformer load. No overload relay function here — this is a short-circuit-only protector for a starter circuit, not a combination motor starter. The clamp terminals accept copper or aluminum conductors up to the frame's rated cross-section — no lug kit needed for most panel builds.","metaTitle":"Siemens 3VA1163-5MH36-0CC0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0CC0 IEC frame 160 MCCB, 63A, 55kA breaking capacity at 415V AC.
