Above that, derate linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Power dissipation at full load is 27.5 W — relevant for enclosure heat rise calculations when grouping multiple breakers.
Interrupting ratings across voltages
The breaker's interrupting capacity varies with system voltage: 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. For a 480 V panel, the 75.6 kA figure at 440 V is the closest published point; coordination studies should use the lower 17 kA at 500 V if the actual line voltage exceeds 440 V.
Auxiliary and trip indication
The auxiliary switches signal the breaker's open/closed state to a PLC or status lamp; the trip alarm switch closes only on a fault trip, distinguishing it from manual opening. This is useful for remote monitoring of downstream faults without adding external relays.
