Straight overcurrent and short-circuit protection for distribution panels, feeder circuits, and main disconnects where you need a clean, no-frills MCCB. Breaking capacity runs 121 kA at 240 V AC, 76 kA at 415 V, 53 kA at 440 V, and 17 kA at 500 V — that's serious fault-current headroom for industrial mains. Full 200 A holds through 50 °C ambient. Above that it steps down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. Dimensions: 158 mm tall, 140 mm wide, 70 mm deep. IP40 on the front — protected against tools and wires, not washdown. Mounts in a standard distribution panel or switchboard; no DIN-rail clip on this frame size, it bolts in.","metaTitle":"Siemens 3VM1220-4EE42-0AA0 SENTRON MCCB, 200A, 4-Pole, 121kA","metaDescription":"Siemens SENTRON 3VM1220-4EE42-0AA0 molded case circuit breaker, 200A, 4-pole, TM220 trip.
