It carries a continuous current of 400 A at 40 °C ambient, with a TM240 thermal-magnetic overcurrent release — so the thermal element is sized for 400 A and the magnetic pickup is fixed at 240 A (the TM240 designation). Breaking capacity is 121 kA at 240 V, 75.6 kA at 415/440 V, 52.5 kA at 500 V, and 11.9 kA at 690 V.
Dimensions are 110 mm deep, 138 mm wide, 248 mm tall. No undervoltage release or communication module on this variant, so no extra wiring for those accessories.
121 kA at 240 V. It also delivers 75.6 kA at 415/440 V, 52.5 kA at 500 V, and 11.9 kA at 690 V.
