  • Description

Selection Notes

This undervoltage release uses a single AC coil rating (380...440 V), narrower than the dual AC/DC 220...240/220...250 V variant in the same XT5 withdrawable family - pick whichever matches the actual control voltage available at the panel. Like all YU releases, it opens the breaker on loss of voltage rather than on command, protecting against an unexpected automatic restart when supply returns.
