YOSHINE Three-Phase Three-Wire Voltage Phase Failure Protection Relay

The Three-Phase Three-Wire Voltage Phase Failure Protection Relay YX701T0380 from YOSHINE is designed to provide reliable protection and monitoring for three-phase electrical systems. It is widely used in industrial equipment, power distribution systems, pumps, compressors, and other machinery that require stable three-phase power to operate safely and efficiently.

This relay adopts a 3P3W monitoring type, allowing it to continuously monitor the voltage conditions of three-phase three-wire power networks. When abnormal conditions such as phase failure, voltage imbalance, under-voltage, or over-voltage occur, the relay responds quickly and triggers the output to protect connected equipment from potential electrical damage.

The working voltage range of 220/380/400/415/440VAC makes this relay compatible with a variety of common industrial power systems, offering flexibility for different applications and installation environments. Its ±15% under-voltage and over-voltage detection capability helps identify irregular voltage fluctuations and ensures that equipment operates within a reasonable electrical range.

Equipped with an SPDT output contact, the relay can easily integrate with control circuits to activate alarms, disconnect loads, or trigger other protection devices when voltage abnormalities are detected. This feature improves system safety and allows operators to respond promptly to power issues.

The YX701T0380 relay is designed with practicality and durability in mind. Its compact structure allows convenient installation inside control panels, while the clear terminal layout simplifies wiring and maintenance. The relay is suitable for applications such as motor protection, pump control systems, HVAC equipment, elevators, and industrial automation panels, where stable three-phase voltage monitoring is important.

By incorporating reliable voltage monitoring and phase failure protection, the YOSHINE Three-Phase Voltage Protection Relay helps reduce the risk of equipment downtime and electrical faults. It provides a practical solution for maintaining stable power conditions in a wide range of industrial and commercial electrical systems.
