Product details

Rated 25 A at 30 °C with a C-curve thermal-magnetic trip unit, it interrupts fault currents up to 6 kA Icn at 230 V AC 50 Hz, complying with both EN/IEC 62606 for arc-fault detection and IEC 60898-1 for MCB performance.

The magnetic trip threshold is set at 5 to 10 times In (125–250 A for this 25 A unit), giving the C-curve characteristic that handles moderate inrush from motor loads or capacitive circuits without nuisance tripping. Electrical durability is rated at 10,000 cycles at 230 V AC; mechanical durability at 20,000 cycles. Tropicalisation to severity B per IEC 60068-2-30 (28-day damp heat cycling) confirms suitability for high-humidity environments — a detail often missed on standard MCB listings.
