NJYB3 Relay (Phase Protection Relay)
General Information
NJYB3 Relay is used to provide overvoltage,undervoltage, phase failure,phase sequence,three-phase unbalance,PTC temperature and load protection control in three-phase three-wire up to 415V circuits and three-phase four-wire up to 240V circuits with a frequency of AC50Hz.
This relay is a voltage protection relay.After detecting the voltage signal,the relay processes the input signal,judges if there is an overvoltage,undervoltage,phase failure,phase sequence,three-phase unbalance,PTC temperature and load error and controls the opration accurately and stably by means of the built-in microprocessor.
NJVA1 (Voltage & Current Protection Relay)
General Information
The NJVA1 voltage and current protector is a new type of intelligent protector. The product adopts a modular design, and can adjust the circuit overvoltage, undervoltage, and overcurrent. The protector can quickly cut off the circuit to avoid equipment damage caused by abnormal voltage or current connected to terminal appliances. When the voltage or current returns to normal, the circuit will be automatically connected within the time delay, so as to ensure the normal operation of the terminal under unattended conditions, and the voltage and current values can be displayed at the same time.
NJMC1 (Pulse Relay)
General Information
Contact switching current of up to 16A and 32A; a complete range of AC/DC specifications; NJMC1 pulse relay is a mechanical bistable relay that changes the contact state by inputting pulse signals.
