three phase monitor relay

Three phase monitor relay

Three-Phase-Monitor Relay Model KRP101 (specific for 3-phase 3-wire networks) This relay is used in three-phase circuits (three wires) that are not functional null, for detecting the following errors and circuit breakdown: Phase loss or asymmetry in network voltage ( ASY.V 5 – 20 %) Phase sequence (P.S) Network voltage under 20% ( UV<300V ) Network voltage over 15% ( OV>440V ) Input power supply connection ( PWR ) It has 6 LEDs for displaying faults (red), output relay connection (green) ,input power supply connection (yellow) Ability to set the connection time after correction error (DELAY) between 0.5 and 30 seconds Three Phase Monitor Relay Model KRP102 (With Null, 4-wire networks) This relay is used in three-phase circuits (four wires) that are functional null, for detecting the following errors and circuit breakdown: Phase loss or asymmetry in network voltage ( ASY.V ) Phase sequence ( SEQU ) Network voltage under ( VOLT ) It has 4 LEDs for displaying faults (red), output relay connection (green) Ability to set the connection time after correction error (DELAY)
