That spread covers common industrial voltages from low-voltage switchgear to 480 V distribution. Current rating holds at 32 A from 40 °C through 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. Power loss is 11 W maximum at rated load. In a densely packed panel, that heat must be considered in the thermal budget — it is modest for a 320 A frame but not negligible in a sealed enclosure with multiple breakers. The breaker has no undervoltage release, no trip indicator, no voltage trigger, no communication function, and no ground-fault monitoring. It is a straight thermal-magnetic line-protection device — no auxiliary electronics to fail or configure. If you need remote signaling or undervoltage protection, you will add external accessories or step to a different variant.","metaTitle":"Siemens 3VM1032-4ED32-0AA0 SENTRON MCCB, 320A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VM1032-4ED32-0AA0 molded case circuit breaker, 320A, 3-pole, TM210 release.
