The TM220 release has a fixed instantaneous pickup at 2000 A (10× In), so it coordinates with downstream branch breakers on a motor-start or transformer-inrush profile without nuisance tripping. Rated current holds flat at 200 A from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C — a curve that matters when the breaker shares an enclosure with other heat sources.","metaTitle":"Siemens 3VM1220-4GE42-0AA0 SENTRON MCCB, 200 A, 4-Pole, TM22","metaDescription":"Siemens SENTRON 3VM1220-4GE42-0AA0 molded case circuit breaker, 200 A at 40 °C, 4-pole, TM220 release.
