The Three Phase Voltage & Phase Monitoring Relays, under the model RNPP-302 is designed for the permanent voltage control and protection of the equipment with rated voltage parameters 220/380 V 50Hz and 230/400V 50Hz. The relays operate with the magnetic coil of the external contactor which in its turn operates with the power load. Three Phase Voltage & Phase Monitoring Relays is manufactured by Sabo Systems Pvt. Ltd.
Sabo Systems Pvt. Ltd., an ISO 9001: 2000 registered organization offers Mimic panels, LT Panels, Control and Relay Panels, Bus duct, Control desk, etc. The Three Phase Voltage & Phase Monitoring Relays constantly checks [before and after turning on] the condition of the power contacts of magnetic contactor and detects the stuck together and burned contacts. When the power parameters return back to normal after the interruption or when the reason of the tripping is eliminated the relays performs automatic re-closing and thus restarts the equipment. It does so following a time delay [0-600 sec], set previously by the user.
