It carries a maximum breaking capacity of 187 kA at 240 V AC, tapering to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the high interrupt rating at the lower voltages makes it a strong fit for fault-current-heavy service-entrance or main feeder positions where available fault current is high. A mechanical trip indicator is present on the front face for quick visual fault identification during walk-throughs.
Thermal performance and panel fit
Maximum power loss is 12.5 W, which is manageable for a DIN-rail or backplate layout but should be factored into the enclosure heat budget if the panel packs multiple breakers side by side. Dimensions are 181 mm high, 105 mm wide, and 86 mm deep (7.13 x 4.13 x 3.39 inches).
