What the interrupting capacity means for your panel
The interrupting capacity is 75.6 kA at 240 V AC, stepping down to 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 3-pole design and 800 V rated insulation voltage suit it for three-phase line protection in switchboards and distribution boards.
Thermal derating and continuous current
Above that, it derates: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. The maximum power loss is 17.3 W, which contributes to the internal heat rise. Mounting in a standard 70 mm deep by 76.2 mm wide DIN-rail footprint; the 130 mm height fits most distribution board cutouts.
