Three poles, rated 160 A continuously at 40 °C, with the TM240 thermal-magnetic overcurrent release — meaning the thermal element is fixed at 240 A frame, adjustable down via the rating plug to match the 160 A continuous load. Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V, so it handles high-fault scenarios on 480 V or 600 V class systems without cascading upstream. Undervoltage release (UVR) is fitted from the factory, which drops the breaker if control voltage falls below the dropout threshold — common for emergency-stop or undervoltage protection schemes. Insulation voltage rated 800 V, power loss at full load maxes at 40.5 W.
At 55 °C it drops to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A.
