The interrupting ratings climb to 75.6 kA at 240 V and 52.5 kA at 415 V, dropping to 11.9 kA at 690 V — so it handles high-fault-current service-entrance or distribution panels, not just downstream feeder duty.
Derate it as ambient climbs: 158 A at 55 °C, 150 A at 70 °C. That matters if this breaker lands in a non-climate-controlled enclosure next to a transformer or drive — you lose 10 A by the time the panel hits 70 °C. The TM240 release means the thermal pickup is fixed at 240 A; the magnetic instantaneous trip is set at the factory. Breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, 11.9 kA at 500 V and 690 V. For a 480 V panel (common in North America), you're looking at roughly the 440 V line — 32 kA SCCR. That's enough for most industrial distribution boards, but verify against your transformer kVA and fault study. The 690 V rating at 11.9 kA covers European 400/690 V IT systems.
Integration notes
If your safety circuit drops power, the UVR trips the breaker open. No communication function onboard, no ground-fault monitoring.
