Front-side protection is IP40, suitable for enclosed switchboards where tools are required to access live parts. Rated current holds flat at 500 A from 40 °C through 50 °C, then steps down linearly: 488 A at 55 °C, 476 A at 60 °C, 464 A at 65 °C, and 452 A at 70 °C. Maximum power loss is 123 W — a figure to account for in enclosed panel heat budgets, particularly when multiple breakers are ganged in a single section. The 70 °C operating ceiling matches the fully derated current at that temperature, so the breaker can be deployed in warm machine compartments or outdoor enclosures without additional ventilation beyond what the heat load requires. ## Integration notes The TM210 trip unit is field-replaceable but factory-set — no dial-adjustable thermal or magnetic settings on this version. For applications requiring adjustable long-time and short-time pickup, the electronic trip variants in the 3VA series would be the next step up.","metaTitle":"Siemens 3VM1450-5ED32-0AA0 SENTRON MCCB, 500 A, 3-Pole, TM21","metaDescription":"Siemens SENTRON 3VM1450-5ED32-0AA0 molded case circuit breaker, 500 A at 40 °C, 3-pole, TM210 thermal-magnetic trip, 187 kA at 240 V.
