The TM210 overcurrent release provides fixed thermal-magnetic protection; no trip indicator or undervoltage release is built in, so external accessories are needed if those functions are required. At 40 °C the breaker is rated 320 A, and it holds that rating through 50 °C. Above 55 °C it derates linearly to 292 A at 70 °C. In a sealed enclosure or high-ambient machine cabinet, that derating curve (–) governs the real load it can carry. Dimensions are 184 mm wide, 248 mm tall, and 110 mm deep; verify the mounting footprint against the panel cutout before wiring.","metaTitle":"Siemens 3VM1332-4GD42-0AA0 SENTRON MCCB, 320 A, 4-Pole, TM21","metaDescription":"Siemens 3VM1332-4GD42-0AA0 SENTRON molded case circuit breaker, 320 A at 40 °C, 4-pole, TM210 release, 76 kA at 415 V.
