The interrupting ratings climb to 121 kA at 240 V AC and 76 kA at 415 V AC — numbers that tell you this breaker can clear high fault currents on a 240 V or 400 V distribution bus without upstream coordination issues. The TM210 release means the thermal pickup is fixed at 50 A; there is no adjustable long-time delay or electronic trip unit, so this breaker is a straight 50 A feeder or branch protector. The 15 W maximum power loss matters for panel heat buildup — if you are packing several breakers in a small enclosure, that loss adds up and may force derating or ventilation. At 76.2 mm wide, 130 mm tall, and 70 mm deep, the 3VM1150-4ED32-0AA0 fits a standard panel footprint for 3-pole MCCBs in the 50 A class.","metaTitle":"Siemens SENTRON 3VM1150-4ED32-0AA0 MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VM1150-4ED32-0AA0 molded case circuit breaker, 50 A, 3-pole, TM210 release.
