The TM220 thermal-magnetic release provides LI (long-time and instantaneous) protection, meaning it handles overload curves and short-circuit trips without electronic adjustment. The switching capacity class S indicates a standard interrupting rating for this frame — not the high-performance class, but the 121 kA at 240 V still covers most commercial and industrial service entrances. Rated insulation voltage (Ui) is 690 V, so the breaker is rated for the insulation coordination of a 480/277 V or 400/230 V system with margin. Maximum operating voltage is 500 V AC 50/60 Hz. The 80 A continuous rating holds from 40 °C through 50 °C — no derating needed at typical panel ambient — and only drops to 74 A at 70 °C. That thermal stability is useful in a crowded enclosure where heat builds up. Front-connected box terminals accept copper or aluminum conductors up to the frame's lug range — no special adapter needed for standard panel wiring. For volume procurement or BOM commitments, we quote this against an RFQ. The part carries the usual Siemens compliance documentation (CE, UL, CSA, IEC 60947-2) though specific cert numbers are on the nameplate.","metaTitle":"Siemens 3VM1180-4EE46-0AA2 SENTRON MCCB, 80 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VM1180-4EE46-0AA2 molded case circuit breaker, 4-pole, 80 A continuous, 121 kA at 240 V AC.
