It carries a 242 kA interrupting capacity at 240 V AC, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — so the SCCR headroom is substantial at typical 480 V industrial feeds, but you need to check coordination at the 690 V end if that's your line voltage.
Sizing and thermal performance
That's unusual for an MCCB; most start tapering above 40 °C. Maximum power loss is 13.5 W, which is modest for a 100 A frame and keeps the enclosure heat rise manageable.
The shunt trip and auxiliary switches are factory-integrated, so no field-add kit to lose or miswire.
