Product details

The breaking capacity steps down with voltage: 40 kA Icu at 240 V AC, 25 kA at 415 V AC, 20 kA at 440 V, and 15 kA at 500 V.

Deployment context

Mounts on a backplate — no DIN rail here. The 4-pole (4P) version with neutral on the left and front-facing connections makes it straightforward to bus and wire in a panel.
