EMR5-A Unbalance Relay – Reliable Phase Loss Detection
Protecting the motor from destruction
The EMR5-A unbalance relay with its 22.5 mm module width is the ideal protective device for phase loss protection. The detection of phase loss on the basis of phase shift means that reliable phase loss detection is ensured and overloads, even when large amounts of energy are regenerated to the motor.
The relay can be used for protecting motors with a rated voltage of UN = 380 V 415 V at 50 Hz.
