Product details

The interrupting ratings are substantial: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. That SCCR headroom means it can sit upstream of a high-fault panel without cascading failure, which is exactly what a site electrical engineer wants for selectivity coordination.

Rated 200 A at 40 °C, it holds that same 200 A at 45 °C and 50 °C — no derating needed in a typical warm panel. At 55 °C it drops to 194 A, then 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The maximum power loss is 44.5 W, so ventilation matters in a sealed box.

That's a standard 4-pole MCCB footprint — it'll drop into a SENTRON panelboard or a DIN-rail adapter without re-drilling the gland plate. A food-and-bev process controls engineer checking panel fill factor can count on that width and depth not eating up extra rail space.
