What sets this one apart is the interrupting capacity: 187 kA at 240 V AC, 121 kA at 415 V, and still 76 kA at 440 V. The 125 A frame is rated continuously at 125 A all the way up to 50 °C, then it derates gradually — 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. At 500 V AC the breaking capacity drops to 17 kA, so check your available fault current if you're on a 480 V or 500 V service — the 440 V number (76 kA) is the more relevant benchmark for most North American 480 V panels. Dimensions: 130 mm tall, 101.6 mm wide, 70 mm deep. The 4-pole width (101.6 mm or 4 inches) is the standard 4-pole MCCB footprint — it'll drop into a panel that's laid out for a 4-pole SENTRON or similar frame. No communication function, no motor drive option, no ground-fault monitoring built in — this is a straight thermal-magnetic breaker for basic overcurrent protection. ## No-frills line protection — what you get and what you don't The product version is explicitly 'Line protection' — not a motor circuit protector, not a switch-disconnector. The TM220 release gives you a fixed thermal element and an adjustable magnetic pickup (li max 1,250 A), but no electronic trip unit, no zone-selective interlocking, no power metering. But if you need adjustable long-time and short-time delays for full selectivity, you'd be looking at an electronic-trip SENTRON 3VA instead.","metaTitle":"Siemens 3VM1112-5EE42-0AA0 SENTRON MCCB, 125A 4-Pole, 187kA","metaDescription":"Siemens 3VM1112-5EE42-0AA0 SENTRON molded case circuit breaker, 125A, 4-pole, TM220 release.
