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:
■ 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.
-It can achieve self starting and self resetting functions.
-Voltage measurement accuracy ≤ 1%.
-The three-phase model has the functions of disconnection and phase sequence detection.
-The fault status can be displayed through LED.
-Installed on a 35mm standard guide rail.
