Product details

It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V, covering most low-voltage fault scenarios from 240 V up to 690 V. Current rating is temperature-dependent: 630 A at 40 °C, derating to 450 A at 70 °C ambient. The adjustable thermal-magnetic trip range spans 945 A minimum to 5 670 A maximum, with a full-scale value of 630 A. Power loss maxes at 162 W.

Mounts in a 138 mm wide by 248 mm tall by 110 mm deep footprint. The 3-pole body fits standard MCCB panel cutouts; verify bus-bar spacing against the 138 mm width before laying out the gland plate.

Accessories and Configuration

No undervoltage release fitted. Communication function is present; no other measurement function.
