It carries a rated insulation voltage of 800 V and delivers an interrupting capacity of 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V — so it handles high-fault-current scenarios common in plant main feeders or large motor control centers.
Above that it derates linearly: 780 A at 55 °C, 761 A at 60 °C, 741 A at 65 °C, and 722 A at 70 °C.
Dimensions are 320 mm high, 210 mm wide, and 120 mm deep. That depth is the key clearance number for enclosure back-panel spacing — make sure your gland plate or rear-mounted buswork leaves at least 120 mm plus wiring bend radius.
