Breaking capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the high 240 V figure tells you this unit is built for high-fault utility or transformer-fed panels, not just branch circuits.
Panel fit and auxiliary complement
Footprint is 105 mm wide × 181 mm tall × 86 mm deep — a standard 3-pole MCCB envelope for a 63 A frame, sized for DIN-rail or screw-mount backpan assembly. Trip indicator on the front face gives a quick visual on whether the breaker opened on overload/short or was manually switched off — saves a multimeter probe during fault isolation.
