Continuous current holds at 50 A from 40 °C through 50 °C ambient, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — the thermal curve matters if the breaker sits near other heat sources in a crowded enclosure. Physical footprint: 130 mm tall, 76.2 mm wide, 70 mm deep — fits standard 3-pole MCCB panel cutouts; the IP40 front face keeps dust out of the trip mechanism in a clean indoor panel. ## Panel Fit & Integration Rated insulation voltage 800 V; operating range -25 °C to 70 °C, storage from -40 °C to 80 °C. Maximum power loss 15 W at rated load — negligible for most panel thermal budgets.","metaTitle":"Siemens 3VM1050-4ED32-0AA0 SENTRON MCCB, 500 A, 3-Pole, TM21","metaDescription":"Siemens 3VM1050-4ED32-0AA0 SENTRON molded case circuit breaker, 500 A frame, 3-pole, TM210 thermal-magnetic trip, 121 kA at 240 V.
