Product details

The interrupting rating drops as system voltage rises: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.

Above that, current must be reduced: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. In a hot panel near a transformer or drive, factor in the actual ambient — a 200 A load at 60 °C would need the next frame size up.

Dimensions: 70 mm deep, 140 mm wide, 158 mm high. The auxiliary switch configuration (2 HQ switches) and the shunt trip occupy the accessory slots; verify clearance above and below for the 70 mm depth when wiring.
