OVERVIEW:NJYB3 relay is used to provide overvoltage, undervoltage, phase failure, phase sequence and threephase unbalance control in three-phase three-wire 380V circuits and three-phase four-wire 220V circuits with a frequency of AC 50Hz.For example, it is used for power control systems, air conditi..
OVERVIEW:This is a voltage protection relay. After detecting voltage signal, the relay processes input signal, judges if there is an overvoltage, undervoltage, phase failure, error-phase or unbalance and controls the operation accurately and stably be means of the built-in microprocessorExplore w11s..
OVERVIEW:NJYB3 relays are used to prevent overvoltage, undervoltage, phase loss, phase reversal and three-phase unbalance control in 3-phase 380V and 3-phase 4-wire 220V circuits with frequency 50 / 60HzRelays are used for air conditioning systems and motors. This is a voltage protection relay, dete..
