At 415 V the breaker still clears 52.5 kA, dropping to 32 kA at 440 V and 11.9 kA at 500 V and 690 V. That means it can serve as the main or feeder breaker in a 480 V panel with available fault current up to 11.9 kA, or in a 240 V panel up to 75.6 kA — a wide selectivity window for most industrial distribution. Thermal derating is modest: the breaker holds 100 A from 40 °C through 50 °C, then drops to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. For a panel running at 50 °C ambient, no derating is needed; at 60 °C you lose 4 A.
Auxiliary Switch and Undervoltage Release — Built-In
The auxiliary switch provides a remote status signal for the PLC or SCADA system. No communication function is included; this is a standalone breaker.
Panel Integration — Footprint and Mounting
Maximum power loss is 27.5 W, which should be factored into the enclosure thermal budget.
