Product details

What the breaking capacities mean for your panel

Its 187 kA interrupting capacity at 240 V and 121 kA at 415 V mean it can safely clear high-fault currents in low-voltage distribution — typical for large transformer-fed switchboards or industrial main feeders where available fault current exceeds 100 kA.

It is a 4-pole unit designed for DIN-rail or screw-mount installation in a distribution board or enclosure.

Trip unit and protection features

The ETU330 electronic trip unit provides adjustable long-time (tr) from 0.5 to 17 s, and supports ground-fault monitoring via summation current on L+N. N-conductor protection is adjustable OFF or 100%. No communication function is built in.
