Rated current holds at 160 A from 40 °C through 50 °C, then derates gradually to 150 A at 70 °C — so in a warm panel you still get full 160 A up to 50 °C, which covers most standard industrial enclosures without derating. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — numbers that tell you this breaker handles high-fault scenarios typical of transformer-fed main feeders or large motor branch circuits. At 500 V and 690 V the capacity drops to 11.9 kA, still adequate for many 480 V and 600 V class installations where the available fault current is known to be lower.
Maximum power loss is 38 W — that's the heat it dumps into the enclosure at full rated current. In a sealed panel with multiple breakers, that figure drives the ventilation or cooling requirement; plan for it if you're packing several high-current MCCBs in a small box.
