Product details

It carries 80 A continuously at 40 °C ambient (derated to 74 A at 70 °C), and its interrupting capacity hits 121 kA at 240 VAC, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that tell you it's built for high-fault industrial service, not light commercial.

Built-in auxiliaries and releases — no add-on modules needed

This breaker includes an undervoltage release and two auxiliary switches (HQ design) factory-installed. The UVR drops the trip coil when control voltage falls below threshold; the aux switches provide remote status signals.

The lifecycle stage is "current" — this is an active, in-production catalog item. No last-time-buy or phase-out notice on record.
