That 200 A holds flat through 50 °C — no derating needed in a typical 40 °C panel — then steps down to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Breaking capacity is the headline: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. At 415 V — common in industrial distribution — that 75.6 kA gives real SCCR headroom for coordinating downstream feeders without cascading upstream. It's a straight line-protection MCCB: wire it in, set the TM220 thermal-magnetic dial, and it protects the feeder.","metaTitle":"Siemens 3VA1220-4EE42-0AA0 SENTRON MCCB, 200 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4EE42-0AA0 molded case circuit breaker, 200 A, 4-pole, TM220 release.
