Rated 100 A continuous at 40 °C, it maintains that rating through 50 °C and derates to 91 A at 70 °C — useful data for a panel builder calculating fill factor and heat rise in an enclosed switchboard.
Breaking capacity is specified across five voltage levels: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That spread tells a site electrical engineer where this breaker can be applied without cascading upstream — the 187 kA figure at 240 V covers most North American 277/480 V panel main applications, while the 17 kA at 690 V suits European 400 V industrial networks with high fault current.
