The interrupting capacity hits 121 kA at 240 V AC, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — still substantial for most industrial distribution panels.
At 415 V the 75.6 kA still gives headroom for most MCC panels.
Current derating curve
At 55 °C it drops to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. No derating needed up to 50 °C, which covers most ventilated indoor panels.
Built-in accessories
The trip alarm switch signals a fault trip separately from manual switching, which simplifies remote monitoring. No ground-fault monitoring on this version; if GF protection is needed, you step to a different suffix.
