Breaking capacity is the headline number here: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That's a lot of fault-clearing muscle — it'll interrupt a serious arc flash without welding contacts or venting gas into the panel.
This MCCB is designed for DIN-rail mounting in standard distribution enclosures. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — roughly 7.1 x 4.1 x 3.4 inches. It'll fit a typical 600 mm wide panel with room for branch breakers alongside. The trip indicator is also absent, so you'll need to read the handle position or add an auxiliary contact if remote status matters. Power loss is negligible at 0.5 W max.
Thermal derating and ambient range
That's unusual — most breakers start derating above 40 °C. Here you get full rated current even in a hot panel near a transformer or drive.
