Voltage monitoring relay D65 series

Phase monitoring relays Eaton’s D65 phase monitoring relays protect loads from voltage fault conditions. The devices provide protection against phase loss, phase reversal, and phase unbalance due to blown fuses, broken wires or worn contacts. They monitor simultaneous voltage drops/increases and help to prevent damaged machinery and the injury of personnel. Core features of phase monitoring relays • Detects reversal of phases when modifications are made to the circuit for worry-free maintenance • Detects motors from running at temperatures above approved ratings for added safety • Detects three-phase motors from continuing to run after losing a phase that could result in motor burnout
