That Icu figure means it can safely clear a bolted fault up to 55 kA without welding its contacts or rupturing the arc chamber — critical for high-fault panels near large transformers or motor control centers. The TM120M thermal-magnetic trip unit provides starter protection: the thermal element tracks motor heating, the magnetic pickup is adjustable from 5 to 15 times In (500–1500 A) for short-circuit-only protection — no overload function in this variant, so upstream or separate overload relay handles running overcurrent. It ships with a 24 V DC undervoltage release (UVR) that drops the breaker on loss of control voltage, plus two auxiliary switches (HQ type) for status feedback to a PLC or annunciator. Terminals are clamp-type, accepting copper or aluminium conductors up to the frame's rating. ## Lifecycle and sourcing posture For a critical-spare holding or a new BOM line, this 3VA1 variant is sourced to order against an RFQ. Availability and current pricing are confirmed at quote time through independent distribution. ## Panel integration notes The 3VA1 frame 160 mounts on a DIN rail or panel baseplate; the clamp terminals accept cable lugs or direct conductor insertion. The UVR coil draws a holding current at 24 V DC — verify the control transformer can supply the inrush without dropping below the UVR's dropout threshold.","metaTitle":"Siemens 3VA1110-5MH36-0BC0 Circuit Breaker, 100A, 55kA @ 415","metaDescription":"Siemens 3VA1110-5MH36-0BC0 IEC frame 160, 3-pole MCCB, Icu=55kA @ 415V, In=100A, TM120M trip, UVR 24V DC, 2 aux switches.
