Breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V (3.7 kA) tells you this is not a 690 V-primary part; it belongs on a 240–500 V distribution side. The auxiliary switch complement (2 auxiliary + 1 trip alarm + 1 electrical alarm switch HQ) and the included shunt trip (STL) release give you remote trip capability and status feedback — useful for a safety circuit or PLC-driven isolation sequence.
Panel integration — dimensions and mounting
Maximum power loss is 4 W, so thermal rise inside a sealed enclosure is minimal — no forced cooling required for a single unit, but account for cumulative heat if multiple breakers are ganged.
