The TM240 thermal-magnetic release handles the overcurrent protection, and the breaker carries an undervoltage release (UVR) as standard, which means it drops out on loss of control power — a common requirement for safety circuits in conveyor and pump panels. Thermal derating is non-linear and starts at 55 °C: the breaker holds its full 160 A up to 50 °C, then drops to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB envelope that drops into a SENTRON distribution panel or a DIN-rail-mount enclosure. Comes with two HQ auxiliary switches (form C) factory-fitted — part number 3VA9608-0BB25 for the integrated auxiliary trip.","metaTitle":"Siemens 3VA1116-5EF42-0DC0 SENTRON MCCB, 160 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1116-5EF42-0DC0 molded case circuit breaker, 160 A rated, 4-pole, TM240 release, 70 mm depth.
