Its breaking capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that place it in the high-interrupting category for industrial distribution panels where fault current levels are substantial.
At 415 V the 154 kA interrupting rating gives headroom for high-fault installations — common in industrial mains where transformer impedance is low. The 690 V rating drops to 17 kA, which still covers most motor branch circuits at that voltage.
Above that it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. If the panel runs hot — near a drive or transformer — factor the derating into the load calculation.
