It carries 80 A continuously at 40 °C, with a slight derating curve: still 80 A at 50 °C, 78 A at 55 °C, down to 74 A at 70 °C — so in a warm panel you lose less than 10 % of the rating. The interrupting capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500 V or 690 V. That gives solid fault-clearing headroom for most industrial distribution panels, especially on the 240 V and 415 V sides where the numbers are high enough to coordinate with upstream gear.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Maximum power loss is 19.2 W; plan for that thermal load in a sealed enclosure.
That means you can remotely trip the breaker and get status feedback without adding external modules.
Environmental Limits
The storage minimum is lower than the operating minimum — that's the handling limit, not the running limit.
