The TM240 thermal-magnetic trip unit gives adjustable overload protection from 175 A to 250 A and a short-circuit pickup adjustable between 5 and 10 times In. It ships with a left-side shunt trip rated 208–277 V AC 50/60 Hz or 220–250 V DC, plus three auxiliary changeover switches — enough to report breaker status back to a PLC or annunciator without adding a separate contactor block. The shunt trip and auxiliary switches are factory-fitted on the left side — verify clearance to the gland plate or adjacent devices before wiring.","metaTitle":"Siemens 3VA1225-5EF32-0KD0 Circuit Breaker, 250A, 55kA @ 415","metaDescription":"Siemens 3VA1225-5EF32-0KD0 IEC frame 250 MCCB, 3-pole, 55kA Icu @ 415V, TM240 thermal-magnetic, adjustable Ir 175-250A, shunt trip, aux switches.
