The TM120M thermal-magnetic overcurrent release provides inverse-time overload protection and instantaneous magnetic trip for short-circuit faults, so the breaker coordinates with a contactor and overload relay in a motor-starting circuit. At 240 V it interrupts up to 220 kA; at 415 V that drops to 154 kA, at 440 V to 75.6 kA, at 500 V to 30 kA, and at 690 V to 4.5 kA — the full range matters when the available fault current at the panel is known.
At 55 °C the rating drops to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A.
Dimensions are 105 mm wide, 158 mm high, and 70 mm deep — a standard 3-pole MCCB footprint for a SENTRON 3VA frame. It ships with two auxiliary switches (HP design) factory-installed, so you get status feedback without adding a separate accessory block.
