Overview

The PBDU Series Phase Monitor Relays protect motors and equipment from damage due to voltage faults on three-phase systems. PBDU relays monitor phase loss, phase reversal, and unbalance. Phase unbalance is adjustable from 5% to 25% and can be disabled altogether if desired.

The compact 17.5 mm enclosure for DIN-rail mounting conserves space and reduces installation time.

LED status indication is located on the front face. Green indicates Power ON. Yellow indicates relay status. Any of the three fault conditions will de-energize the relay after a fixed trip delay of 100 ms. Re-energization is automatic upon correction of the fault condition.

Monitored voltage is universal: 208V to 480V AC.
