Rated 80 A continuously at 40 °C ambient, it derates slightly as the panel warms: 78 A at 55 °C, 74 A at 70 °C — useful to know if this breaker sits in a crowded enclosure with other heat sources. At 240 V it interrupts 220 kA — that is a very high rating, typical for a main breaker in a large industrial distribution board. Three-pole construction covers three-phase circuits. The auxiliary switch configuration is 1 auxiliary + 1 trip alarm switch HQ — that gives you one NO/NC contact for status feedback and a separate contact that only changes state when the breaker trips on fault, useful for remote alarm annunciation. The trip indicator gives a local visual flag.
Where it goes in the panel
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most distribution boards.
