This MCCB interrupts 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel, the 32 kA SCCR gives headroom for most industrial transformer ratings.
The 100 A rating holds steady from 40 °C to 50 °C (–), then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C (–). Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panels. Maximum power loss is 25 W, which is modest for a 100 A frame; no special heat sink needed.
