Wenzhou Kinee Electrical Co., Ltd. is one of the most reliable manufacturers and suppliers of double-break voltage guard in China. We warmly welcome you to wholesale double-break voltage guard for sale here from our factory. All customized products are with high quality and competitive price.
Product Introduction
This Double-Break Voltage Guard can simultaneously cut off the phase line and neutral line to achieve complete electrical isolation, eliminate the hidden danger of residual electricity in the line, and achieve a higher level of safety protection. The equipment has high-precision overvoltage and undervoltage detection functions, and can quickly cut off power when the voltage is abnormal, effectively protecting all types of electrical equipment. After the voltage returns to normal, it can delay automatic reset to avoid frequent tripping and power-on shocks. The product is installed on standard guide rails, with stable operation and long service life. It is suitable for various scenarios with high requirements on electricity safety, such as household, commercial and conventional industries.
