Wenzhou Kinee Electrical Co., Ltd. is one of the most reliable manufacturers and suppliers of single-pole over/under voltage in China. We warmly welcome you to wholesale single-pole over/under voltage for sale here from our factory. All customized products are with high quality and competitive price.
Product Introduction
The single-break (1P+N) self-resetting over/under voltage protector is designed for single-phase 220V circuits, cutting off only the live wire and keeping the neutral wire directly connected. It is compact and easy to install. It provides rapid trip protection when the voltage exceeds the 165~275V range, and automatically resets after a delay once the voltage returns to normal, preventing damage to electrical appliances due to abnormal voltage. It is resistant to instantaneous voltage fluctuations, less prone to malfunction, and offers high cost-effectiveness. It is widely used in household and general single-phase power distribution scenarios.
