At 240 V it interrupts 242 kA — enough for a high-capacity transformer secondary. At 415 V and 440 V it holds 187 kA, dropping to 121 kA at 500 V. At 690 V it's still rated 3.7 kA, which covers most motor-circuit faults on a 690 V bus.
Thermal performance and derating
Maximum power loss is 25.5 W, which is manageable for a 160 A frame but worth checking against the enclosure's thermal budget if you're packing multiple breakers in a sealed box.
Integration and dimensions
Dimensions: 105 mm wide (4.13 in), 181 mm tall (7.13 in), 86 mm deep (3.39 in). The shunt trip occupies the auxiliary release slot — no undervoltage release (UVR) on this variant.
