EKR8-5 Trigger Time Relay
Inquire
Single Phase Voltage Monitoring Relays are designed for protection of single-phase load against un-allowable voltage variations in the mains. They have a wide range of adjustments, including power on time delay for protection of refrigerating, compressor and air-conditioning equipment.
1. Cut off the line when Over & Under Voltage occurs, and automatically reset and connect the line after
returning to normal without manual operation.
2. When the line appears transient or transient Over& Under Voltage, the protector does not malfunction.
