Reviews Three Phase Relay

Omron K8DS-PH1 Phase Monitoring Relay

The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail..
Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage..
Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S..
Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC..
Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action..

Working Range: Suitable for using in power system with rated isolation voltage up to 690V, circuit of 50-60hz.
Longer Service: Can be used as overload protection of your long term or indirect long term service motor.
Protection Function: Used for protecting the phase break when the electric motor is overload.
Temperature Compension: The relay has different mechanism and temperature compensation.
Multifunctions: With phase break protection, manual and automatic reset, temperature compensation, trip indication, test button and stop button.

◆ Function: phase sequence detection, live line check, simple performance check, live cable identification, phase loss assessment, search for cable break position, detection of DC line break point, line maintenance.
◆ Non-Contact Inspection: Non-contact inductive measurement of the terminal type without opening the cable, without touching the exposed high voltage fire cable, with the three highly insulated super inductive terminals inserted directly into the cable insulation skin 3-phase live detection for safe and quick productivity..
◆ Positive and Negative Phase: With the LED display, dynamic sound and light perfectly show the positive or negative phase of the phase sequence of the three-phase power supply, which can be seen at a glance..
◆ Magnetic base: The base plate of the instrument is equipped with 4 magnets that can stand a quality of 800 g. They can be attached to the metal case of the device during the test, and it is convenient and convenient to use..
◆ Wide Voltage Test: This phase meter can detect three-phase voltages from 70V to 1000V and has excellent performance..
