Samwha-Dsp FKV-11 3*380VAC Non-Neutual Three-Phase Phase Failure, Phase Asymmetry (Fixed. 30%) Relay

General

FKV-11 phase failure relays are designed to avoid any failure of three phase motors caused from network.

Usage and Working Principle

Make the connections of the device in accordance with connection scheme.

When power is on and phases in normal values, relay pulls and relay led is switched on. In this case, contact out is (NO)3. Any of the phases increases or decreases than normal values, relay releases and led switches off. In this case contact out is (NC)1 .

Maintenance

Switch off the device and release from connections. Clean the trunk of device with a swab. Don’t use any conductor or chemical
might damage the device. Make sure device works after cleaning

Warnings

Please use the device according to the manual.
Don’t use the device in wet.
Include a switch and circuit breaker in the assembly.
Put the switch and circuit breaker nearby the device, operator can reach easily.
Mark the switch and circuit breaker as releasing connection for device.
