Surge Protection Device
Reliable surge protection solutions designed to safeguard electrical systems and sensitive equipment from lightning strikes and voltage surges.
What is Surge Protection Device?
A Surge Protection Device (SPD) is designed to protect electrical systems and electronic equipment from voltage spikes caused by lightning strikes, switching operations, and transient surges.
The surge protection device safely diverts excessive voltage and fault current to the ground, preventing damage to electrical installations, switchgear, control panels, and sensitive electronic devices.
Renown Earth is a trusted manufacturer & supplier of Surge Protection Devices in India, providing reliable and high-performance surge protection solutions for industrial, commercial, residential, and electrical applications.
Surge protectors are also known as spike suppressors, surge suppressors, or surge diverters. They help protect appliances and electrical networks by redirecting surge currents safely to the earth.
SPD systems are widely used in industrial plants, commercial buildings, power distribution systems, telecommunication infrastructure, LED lighting systems, and sensitive electronic installations.

Types of Surge Protection Devices
There are four major types of Surge Protection Devices used for protecting electrical systems and sensitive equipment from transient overvoltage and lightning surges.
Type 1 SPD is installed at the main service entrance and protects against external surges caused by lightning strikes. Type 2 SPD is installed on the load side to protect branch circuits and electrical panels.
Type 3 SPD protects sensitive electronics like televisions, computers, and appliances from low-level surges, while Type 4 SPD is used for industrial electronics such as PLCs and servo motors.

Got Questions? We've Got Answers
Find answers to common questions about surge protection devices.
What is a Surge Protection Device?
A Surge Protection Device (SPD) is used to protect electrical systems and equipment from voltage spikes caused by lightning strikes and transient surges.
How does a surge protection device work?
When voltage exceeds the safe limit, the SPD immediately diverts excess energy and surge current safely to the ground.
What are the types of Surge Protection Devices?
There are four major types: Type 1 SPD, Type 2 SPD, Type 3 SPD, and Type 4 SPD.
Where are Surge Protection Devices used?
SPDs are used in industrial plants, commercial buildings, power systems, LED lighting, telecommunication systems, and residential electrical installations.
Do surge protectors really work?
Yes, surge protectors effectively protect electrical and electronic equipment from voltage spikes and transient surges by safely diverting excess current to the earth.
