SVRD Single phase overvoltage and undervoltage protectorDetailed product description：

Protection features:
Overvoltage protection
Undervoltage protection

Dimensions: 79H × 23W × 79D
Warning! This product is generally used for sampling the power side of single-phase power supplies and should not be installed on the output side of variable frequency currents!  

Product Overview
The SVRD series single-phase overvoltage and undervoltage protector is mainly used for various fault detection of AC 50/60Hz, rated voltage below 250V, industrial single-phase 110V, 220V, 240V, 250V and other voltage levels. It provides relay protection for high and low voltage of single-phase input power supply. This product is an indispensable protection product for maintaining the normal working voltage of industrial equipment during operation. This product complies with the GB14048.5-2001 eqv IEC60947-1:1999 standard.

Voltage Range Selection Table

Contact form: Two open and two closed
Note: 1. Overvoltage and undervoltage protection will take about 3 seconds to activate
2. As this protector only protects against voltage and its phase sequence, it can be applied to devices of various powers.

structural characteristics
1. Installation method: The protector base adopts a guide rail type and is equipped with two M4 screw hole structures. It can be installed independently or on HT35 guide rails (if direct installation is used, the accessories on both sides of the bottom of the product need to be forcefully pushed out).
2. Indicator lights: Five indicator lights are used to indicate: normal, phase loss (voltage three-phase imbalance), reverse phase, overvoltage, undervoltage.
3. Dimensions: 79mm × 23mm × 79mm.
