Features
Application
Surge Arrester SA-0.2810 is a voltage and current protector,it features functions such as overcurrent, overvoltage and undervoltage protection. when the current/voltage deviates from the set value, the relay automatically disconnects the power to prevent fires and safe guard electrical devices.it also has an auto-reset function, which means that when the voltage and current return to normal values, the power is automatically restored.
Metal oxide surge arresters are commonly used in electrical networks and devices to protect them from high-voltage surges. The metal oxide semiconductor material in the arrester acts as a resistor. and it's designed to absorb energy from any surge of voltage or current that exceeds safe levels This helps prevent damage to sensitive components and equipment.
