PBDU Phase Monitor Relays: Save Space, Quick Installation and Reduced Costs.

Wednesday: November 10, 2021 : Blog


PBDU Series Phase Monitor Relays protect equipment from damage due to voltage faults. These narrow relays save panel space, reduce installation time and cut costs.

The 17.5 mm wide enclosures mount on 35 mm DIN-rail. These relys can be panel mounted with two screws by extending the clips from under the relays. 

 

The PBDU Series protects against phase loss, phase reversal and phase unbalance. Phase unbalance is adjustable from 5% to 25%.  Full fault indication on top of units facilitates easy troubleshooting. These relays are compatible with most Wye or Delta systems with no connection to neutral required.
