Product details

Rated 50 A continuous at 40 °C, it holds that rating through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C, so if your panel ambient runs hot you need to account for that thermal curve. Breaking capacity is the headline: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Integration and panel fit

Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The overcurrent release is a TM240 thermal-magnetic type, so it provides both overload (thermal) and short-circuit (magnetic) protection without external trip units.
