It carries a 52.5 kA interrupting capacity at 240 V AC, stepping down to 32 kA at 415 V and 13.6 kA at 440 V — enough to handle high-fault industrial feeders without cascading upstream. An undervoltage release (UVR) is built in, plus two auxiliary switches and a separate trip alarm switch (HQ version) for remote status feedback.
At 55 °C it drops to 48 A, then 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
Panel fit and mechanical
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The 76.2 mm width (3-inch pitch) matches typical busbar spacing. The undervoltage release is factory-installed; no field wiring of a separate UVR module. Auxiliary contacts are the 2-switch + trip alarm variant, so you get both status and fault indication without adding a separate accessory block.
