It carries a TM240 thermal-magnetic overcurrent release and is rated 160 A continuous at 40 °C, with a thermal derating curve that holds 160 A up to 50 °C, then steps down to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C — so in a warm panel you lose less than 7 % of the rating at the top end.
Auxiliaries and dimensions
Power loss is 38 W maximum at rated load. Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — about 4 by 5.12 by 2.76 inches. That's the standard 4-pole SENTRON 3VA frame size; it drops into the same mounting cutout as other 3VA breakers of this pole count. Trip indicator is present on the front, so you can spot a tripped breaker without opening the door.
