Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V, and 187 kA at 500 V, making it suitable for high-fault installations like main feeders or large motor branch circuits.
At 55 °C it derates to 60.48 A, and at 70 °C to 56.7 A — so in a hot panel (e.g., near a drive or transformer), you must account for the reduced ampacity. Breaking capacity at 690 V is 52.5 kA — still substantial, but a fraction of the 330 kA at 240 V.
The breaker occupies a 105 mm width, 181 mm height, and 86 mm depth footprint — standard for a 3VA frame size. It mounts via screw terminals or optional plug-in base; no DIN-rail clip, so panel cutout and bus-bar planning are required. The 75 W maximum power loss must be ventilated in a sealed enclosure.
