Three-phase Three-wire Protection Relay: Equipped with overvoltage, undervoltage, phase failure, and phase error protection. Overvoltage and undervoltage settings, as well as action protection delay, can be independently set by the user as needed. When voltage faults (exceeding the set value), phase failure, or phase error occur in the three-phase line, the load is automatically disconnected. It can also automatically monitor the line voltage environment and automatically close when all voltage parameters return to normal, restarting the load. Mainly used for protecting the next level of electrical equipment in three-phase distribution lines.
Wenzhou Derrek Electric Co., Ltd. is an OEM/ODM YOSHINE Three-Phase Three-Wire Over/Undervoltage Protection Relay Supplier and Wholesale YOSHINE Three-Phase Three-Wire Over/Undervoltage Protection Relay Company. YOSHINE’s products can be divided into two categories:
