At 40 °C it carries 100 A continuous, derating to 91 A at 70 °C. Breaking capacity hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, and holds 7.5 kA up to 690 V — solid fault-clearing headroom for most industrial distribution panels.
Above 55 °C you lose about 2 A per 5 °C rise — at 70 °C it's 91 A, so if your panel runs hot, size the load accordingly. The 4-pole design lets you switch all three phases plus neutral in a single unit, common in North American 480Y/277 V or European TN systems.
The breaker measures 101.6 mm wide, 130 mm tall, 70 mm deep — fits standard panel-mount cutouts for 4-pole MCCBs.
