At 415 V and 440 V it still holds 242 kA, dropping to 187 kA at 500 V and 3.7 kA at 690 V, so the voltage-dependent rating governs where you place it in the system. That simplifies panel layout in warm enclosures or outdoor cabinets. It includes a ground-fault monitoring function using summation current formation on L + N conductors, and a communication function for integration into a higher-level monitoring system — useful for predictive maintenance or remote trip indication on a critical feeder.
Dimensions are 86 mm deep, 140 mm wide, 181 mm tall — a standard MCCB footprint for a 4-pole 40 A frame. The 140 mm width means it occupies roughly three 45 mm module spaces, so plan your enclosure fill factor accordingly. No undervoltage release or voltage trigger on this variant — it's a straight thermal-magnetic or electronic trip unit with ground-fault summation.
