It carries 160 A continuously at 40 °C and derates slightly to 150 A at 70 °C — a thermal curve that matters when you're packing breakers into a warm panel without forced cooling. Breaking capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V.
Fit and integration
Power loss and protection features
Maximum power loss is 38 W at rated current — that's heat that has to be managed inside the panel. It's a straight thermal-magnetic breaker for basic line protection.
