Reliable Three Phase Voltage Monitoring Relay of three-phase mains phase failure DIN rail mount

 

The voltage and phase monitoring relay is the Device protect the motor for phase dead protection , low voltage protection , high voltage protection 

 

--With the Compact modular size and the relay is monitoring the phase reversal and phase failure ,when it happened ,the LED  will light up to indicate the question

Phase failure relay is powered by measuring circuit and has 2 C/O contacts

Applied to Pump fans blowers motor air conditions compressors for protective the three phase circuit from phase reversal and phase failure

High quality guarantee and arrival the CE CCC Approvals keep safety when you used it

 

The purpose of phase protection
In the operation of the three-phase motor, as long as one of the following conditions, such as contactor contacts burned and caused a phase contact failure, installation and maintenance causes a phase disconnected or three-phase power supply fuse of a phase fuse, will Causes the three-phase motor to run in phase. If it is found not to be timely, it will also cause the burning of the motor and the damage of the equipment, which will affect the continuous production and cause a certain loss.

 

In order to ensure the safe operation of the motor, generally important motors are equipped with various phase failure protection devices to prevent the motor from being burned out in the event of a phase loss and to minimize unnecessary losses.

 

Today's motor phase-loss protection circuit has complicated circuits, many components, and low working reliability. Most of them use electronic protection devices, or due to abnormal operation, the motor cannot be closed or protected against movement, which affects the smooth progress of production.
The protection device described in this article not only has many features such as fewer components, simple principle, basically no maintenance, reliable operation, etc., but also can achieve reactive power compensation by configuring the components as much as possible.
The principle of this protection device is: the neutral point of the three-phase star wiring, the potential is basically low when the three-phase load is balanced, and when the three-phase power supply lacks phase, the neutral point potential will rise to the phase voltage. Monitoring the power supply of the power supply according to this feature can play a role in phase loss protection.
