XENHO's Over and Under Voltage Relay employs high-precision voltage detection technology to monitor grid voltage fluctuations in real time. When the voltage exceeds 275V or falls below 170V, it automatically cuts off the power supply, effectively preventing damage to electrical appliances due to overvoltage or undervoltage.

​A high-quality Digital Over and Under Voltage Protector is offered by XENHO, a leading manufacturer in China. Specifically designed to ensure electrical safety in modern residential and industrial settings, this device employs high-precision voltage detection technology to monitor power grid fluctuations in real time. When the voltage exceeds 275V or drops below 170V, it automatically cuts off the power supply, effectively preventing damage to electrical appliances caused by overvoltage or undervoltage.

XENHO is a professional manufacturer specializing in the R&D and manufacturing of high-end electrical equipment in China, dedicated to providing safe and reliable power solutions for the global industrial, commercial, and infrastructure sectors. Our AC Type 4P Residual Current Circuit Breaker RCCB—distinguished by its exceptional breaking capacity, stable overload protection performance, and intelligent control technology—is ideally suited for the protection of main distribution lines and for integration with critical equipment.

As a professional manufacturer based in China, XENHO's Normally Closed Auxiliary Switch enables seamless integration with protection systems, facilitating effective monitoring, signaling, and interlocking control within electrical networks. Its core structure employs a high-sensitivity electromagnetic triggering mechanism to ensure rapid response under abnormal operating conditions, preventing equipment damage or fire risks.

As the professional manufacturer in China, XENHO would like to provide you high quality NC Circuit Breaker, which is a safety protection device designed to remain in an open (disconnected) state under no-current or power-loss conditions. It only closes automatically when the power supply is stable and no fault is detected.

As the professional manufacturer in China, XENHO would like to provide you high quality 4 Pole Contactor, which is a high-performance electromagnetic switching device designed for AC 380V circuits, with a rated current range of 5A–63A. It is engineered for frequent switching of motor loads and provides stable, low-noise operation in demanding industrial environments.
