Three-phase Three-wire Protection Relay: Features overvoltage, undervoltage, phase failure, phase error, and imbalance protection. The overvoltage and undervoltage settings, as well as action recovery delay, can be independently configured by the user. When voltage faults, phase failure, or phase error occur in the three-phase line, the relay automatically disconnects the load. Once all parameters return to normal, it automatically reconnects. Ideal for protecting downstream equipment in three-phase distribution lines, with universal operating voltage for global use and clear fault indicators.
Wenzhou Derrek Electric Co., Ltd. is an OEM/ODM YOSHINE Three-Phase Three-Wire Protection Relay Supplier and Wholesale YOSHINE Three-Phase Three-Wire Protection Relay Company. YOSHINE’s products can be divided into two categories:
1. Products that manage electronic control processes (Step Relay, Time Relay, Switching Power Supply, Floatless Level Switch, etc.).
2. Products that protect equipment (e.g. motors) from voltage and current failures (Voltage Protection Relay, Current Monitoring Relay). OEM service is offered according to the client’s requirements.
YOSHINE has made its contribution to the development of our society and the global intelligence industry with the mission of “Made for Connection”.
