The TM210 thermal-magnetic release provides LI (long-time and instantaneous) protection — the thermal element tracks overloads, the magnetic element trips on short-circuit. The adjustable instantaneous pickup maxes out at 800 A, per the datasheet. ## Thermal derating curve — continuous current across ambient temperature Above that, the continuous current derates linearly: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power loss is 6 W. ## Panel integration — footprint and environment The breaker occupies a 25.4 mm wide (1 in) DIN-rail slot, 130 mm tall and 70 mm deep. No auxiliary contacts are fitted as standard (zero CO contacts), and no motor drive or communication module is included on this variant.","metaTitle":"Siemens 3VM1180-4ED12-0AA0 SENTRON MCCB, 80 A, 1-Pole, 76 kA","metaDescription":"Siemens SENTRON 3VM1180-4ED12-0AA0 molded case circuit breaker, 80 A rated at 40 °C, 1-pole, 76 kA breaking capacity at 240 V.
