This breaker carries 187 kA interrupting capacity at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. At 415 V, 121 kA covers most industrial service-entrance and sub-distribution fault levels; the 17 kA at 690 V still handles typical motor-circuit faults in 690 V drives.
Thermal derating and ambient range
Above that, it derates: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. For a 100 A feeder in a warm enclosure, you lose about 10 % capacity at 70 °C — factor that into your busbar and cable sizing.
Protection and release package
A voltage trigger is present for undervoltage or overvoltage sensing. No ground-fault monitoring module is integrated — if you need GF protection, that's an external accessory. Maximum power loss is 75 W at rated current.
The 86 mm depth keeps it within typical enclosure clearances for 100 A class breakers.
