Surge Protection Devices
Surge protection devices, or SPDs, are safety devices designed to protect electrical equipment from electrical surges, generally referred to as transient overvoltages, running across the system. Transients, a safety hazard, can significantly damage the device. These transient overvoltages are overcome due to the surge protectors that conduct them to the earth, thus limiting the voltage to normal.
Where are surge protection devices installed?
Normally, SPDs are installed within consumer units; however, they can also be set up in a separate enclosure in the case of limited space.
What are transient overvoltages? How are they produced?
Transient overvoltages are short-term electric surges that result from abrupt energy release through alternate ways. They are generated either naturally by lightning strikes, switching sources, or man-made.
What are the types of surge protection devices?
SPDs are classified into four main types, including:
- Surge protection modules
These surge protector modules protect point-of-use devices, allowing protection against current spikes and overvoltages.
- Branch surge panels
These panels are prefixed to the service entrance load side and are designed to protect against internally produced and motor-driven surges.
- Secondary surge arresters
They are preinstalled on the service panel’s line side and are responsible for protecting against switching or lightning events.
- Power strips
These strips are designed to significantly protect sensitive (with lower voltage & ampere) electronics by blocking current spikes.
Applications of surge protection devices:
SPDs are suited for the protection of a wide variety of electronic devices in specific applications, such as:
- Computers
- TVs
- Safety Circuits
- Washing Machines
- Distribution System
- Industrial Systems
- Power Distribution Panels.

Surge Protection Devices, SPDs (DIN-rail)
Voltage surges, often referred to as spikes or transients are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning and can reach up to 6000V, with current surges of over 3000A. The maximum size of the voltage and current surges depends on the location within the building's wiring system. BS7671: 2011 Amendment 1 Sections 443 and 534 cover risk assessment and provides guidance on protection of electronic equipment for installation engineers to follow. The fullest information on lightning and surge protection comes from the BSEN 62305 series of standards.
