Surge Suppressor Definition

Device Purpose: Electrical equipment finds protection against sudden voltage changes and overvoltage events via surge suppressors, which serve as protective devices.
Excess Voltage Limitation: Excess voltage hits a limit on the surge suppressor before it reaches electronic devices, which protects them from getting damaged.

Working Principle

Voltage Redirection: During current changes, the surge suppressor activates by sending excess voltage to the ground line to defend equipment from damage.
Excess Energy Emission: The device draws and doubles voltage spikes to then emit the excess electrical energy, thus safeguarding connected equipment from harm.

Types

Socket-Type Surge Suppressor: A socket-type surge suppressor becomes part of your plug to protect equipment in an effortless manner. The device protects compact areas such as residential and office settings.
Power Line Surge Suppressor: A power line surge suppressor provides entire electrical system protection from sudden voltage fluctuations as it gets installed in power supply lines.
Signal Line Surge Suppressor: A signal line surge suppressor serves as a protection solution that safeguards data and communication lines against signal interference and data corruption events.
