160 A MCCB with 2 auxiliary switches and shunt trip
Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — that 187 kA figure at 240 V covers high-fault utility feeds and transformer secondaries where fault currents can spike. That simplifies panel thermal budgeting: you can load it to 160 A even in a 70 °C enclosure without recalculating.
Max power loss is 25.5 W, which helps when sizing enclosure ventilation or forced cooling for a multi-breaker lineup.
