The TM240 thermal-magnetic trip unit provides overload protection adjustable from Ir=560A to 800A, and fixed short-circuit protection at Ii=5 x In. The TM240 thermal unit's adjustable Ir range (560-800A) lets you match the breaker to the actual continuous load, not just the frame size; set it to the cable or busbar ampacity, not the transformer nameplate. The shunt trip coil draws from a separate control circuit (220-250V DC or 208-277V AC), so verify your control voltage matches before wiring — a common miss on retrofit swaps.","metaTitle":"Siemens 3VA1580-5EF32-0KA0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA1580-5EF32-0KA0 IEC frame 1000 circuit breaker, 3-pole, 800A, Icu=55kA @ 415V, TM240, shunt trip.
