Rated 100 A continuously at 40 °C, it holds that rating through 50 °C before derating begins at 55 °C (98 A) and down to 91 A at 70 °C. The front face is IP40, finger-safe but not washdown-rated; mount inside a closed panel.
Breaking capacity across voltages
This breaker's interrupting rating varies with system voltage: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V.
The 101.6 mm (4-inch) width is standard for a 4-pole MCCB in this class — it fits the common DIN-rail or mounting-plate footprint without surprises. No undervoltage release or communication module fitted on this variant; it is a standalone thermal-magnetic breaker.
