What this MCCB does — and where the numbers matter
It carries 50 A continuously at 40 °C and holds that rating all the way up to 50 °C — at 55 °C it derates to 49 A, at 70 °C it's still good for 45 A. That's a solid thermal curve for a warm panel or a crowded enclosure. Breaking capacity is where this unit earns its keep: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. That means remote tripping and status feedback are wired in from the factory — no extra add-on modules to buy and fit. It's a straight line-protection breaker, sized for the main feed.
Footprint is 70 mm deep by 76.2 mm wide by 130 mm tall — standard 3-pole MCCB envelope for a 50 A frame.
