Product details
overview
■Scope of application:
The self resetting overvoltage and undervoltage protector is suitable for users or loads with single-phase AC voltage of 220V, frequency of 50Hz, and rated working current of 60A and below. As a protection for single-phase electrical equipment against overvoltage and undervoltage caused by neutral line faults. Mainly used for the protection of residential sub boxes or distribution lines that require protection of single-phase electrical equipment.
■Features and advantages:
-Dual manifold design enhances wiring capability
-Up line/down line optional
-Can achieve self starting and self resetting functions
-The three-phase model has the functions of disconnection and phase sequence detection
-Monitor the working voltage of oneself and measure the true effective value
-High precision: 1%
■ Application
-Overvoltage and undervoltage protection for household appliances.
■ Functional Features
-Power supply voltage measurement protection (true RMS voltage measurement).
-The dual manifold design has stronger wiring capability.
