At 55 °C it still carries 194 A; at 70 °C it's 176 A. That thermal curve matters when this breaker lives in a crowded panel next to a hot drive or a transformer. The interrupting ratings are serious: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The 'TM' means fixed thermal and magnetic settings, no electronic adjustment. For a line-protection role on a fixed-load feeder, that's the right call: set it and forget it. ## Built-in undervoltage release and panel fit Handy for a safety circuit or a pump panel that needs to drop out on a brownout. It'll drop into a SENTRON panel or a generic enclosure without re-drilling the mounting plate.","metaTitle":"Siemens 3VA1220-5EF42-0BA0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1220-5EF42-0BA0 SENTRON molded case circuit breaker, 200 A at 40 °C, 4-pole, TM240 release, 187 kA at 240 V.
