Surge Suppressor Definition

A surge suppressor is a device used to protect electronic equipment from sudden voltage changes and overvoltage events.
By limiting excessive voltage, it prevents the surge from spreading to electronic devices, safeguarding them from potential damage.

Working Principle

Detects changes in current, and when the voltage exceeds the set threshold, the surge suppressor diverts the excess voltage to the ground line to protect the equipment.
By absorbing and dissipating voltage spikes, it instantly releases excess electrical energy, preventing it from causing damage to the connected devices

Types

Socket-type Surge Suppressor: Plugs directly into the power socket, providing quick and easy protection. Ideal for use in small spaces like homes and offices.
Power Line Surge Suppressor: Installed within the power supply line, offering protection for the entire electrical system against sudden voltage fluctuations.
Signal Line Surge Suppressor: Specifically designed to protect data and communication lines, preventing signal interference and data corruption.
