Its interrupting capacity reaches 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC — figures that govern fault-clearing capability at the point of common coupling.
The 25 A rating holds across 40 °C to 50 °C ambient; above that it derates to 24 A at 55–60 °C and 23 A at 65–70 °C.
Integration and auxiliary configuration
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.
