Its interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — figures that govern the available fault current it can safely clear without upstream coordination failure. Maximum power loss is 13.1 W. The 70 mm depth, 76.2 mm width, and 130 mm height fit a compact 3-pole footprint — check gland-plate clearance if retrofitting into a densely packed panel.
At 55 °C it derates to 31 A, at 65 °C to 30 A, and at 70 °C to 30 A.
