Monitoring Relays

Control relays and timers

Eaton’s D65 series phase monitoring relays prevent motors from running at temperatures above approved ratings. 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.
