There are three different types of Surge Protective Devices:
- Type 1 SPD installed at the origin, e.g. main distribution board.
- Type 2 SPD installed at sub-distribution boards. (Combined Type 1 & 2 SPDs are available and are usually installed in consumer units).
- Type 3 SPD installed close to the protected load.
What is a type 1 surge protection device?
Whole house surge protection type 1 refers to a SPD (surge protective device) that mounts onto the outside meter of your home (pictured below). This is the first line of defense against surges. It’s a meter based surge protector that reduces extra voltage (surge) from the power grid, before it reaches your main electrical panel.

Do you plug your laptop into a surge protector?
You should plug your gadgets into a surge protector, which isn’t necessarily the same thing as a power strip. Sure, we all might forget about surge protection because everything seems to be going fine, but it only takes one power surge or spike and your expensive electronics could become useless.
What is Type 1 and Type 2 surge protection?
What is the difference between Type 1 and Type 2 Surge Protective Devices? Type 1 devices are installed before the main device in the loadcenter, whereas Type 2 are installed following the main devices in the loadcenters.
What is the difference between a Type 1 and Type 2 surge arrester?
Type 1 & 2 surge arresters are installed directly under the incoming breaker. We use Type 1 when there is a lightning bolt installed on the building roof. When there's not, we use Type 2. Type 3 is installed in parallel with the sensitive loads ( Computers, printers...etc. )
What is a Type 2 surge protection device?
The Type 2 Surge Protection Devices are the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of any overvoltages in the electrical installations and protects the loads. Type 2 SPD is characterized by an 8/20 µs current wave.
What is Level 1 surge protection?
Type 1 surge products are permanently connected devices that are installed before or after a main disconnect. These devices can be used as replacements for what were previously known as secondary surge arrestors or lightning arrestors. Applications Include: • Loadcenters/Electrical Panels.
What are the 3 different types of surge protectors?
There are three different types of Surge Protective Devices:Type 1 SPD installed at the origin, e.g. main distribution board.Type 2 SPD installed at sub-distribution boards. (Combined Type 1 & 2 SPDs are available and are usually installed in consumer units).Type 3 SPD installed close to the protected load.
What is Type 3 surge protection?
Type 3 Surge protector device (SPD) Type-3 SPD is characterized by a combination of voltage waves (1.2/50 µs) and current waves (8/20 µs). • Its main function is to limit low level surges which can damage sensitive electronic circuits in TVs, PCs and electric appliances.
What is Type 4 surge protection?

How do I choose SPD rating?
Selection of Surge Rating for an SPD depends on The location of the SPD within the electrical distribution & environmental surroundings condition of Site. Following surge current ratings based on SPD location within the electrical distribution.
What are the different types of surge protectors?
The different types of surge protectors include whole-house surge protectors, surge protector strips and wall-mount surge protectors. Some types have a battery backup, providing an uninterruptible power supply. Most surge protectors use a Metal Oxide Varistor, or MOV, to divert excessive voltages.
Are there different levels of surge protectors?
All surge protectors are not created equal. In fact, there is a tremendous range in both performance and price of protection systems. At one end, you have your basic $5 surge protector power strip, which will offer very little protection.
What surge protection do I need?
Units with surge protector ratings of 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers. Consider the highest joule ratings—2000 and above—for home theater components, gaming consoles and any computer that stores important data…
How big of a whole house surge protector do I need?
The recommended minimum protection from a whole-house system is 40,000 amps, though many are much higher. A lightning strike is usually around 30,000 amps. That said, it's always advisable to unplug what you can if a lightning storm is imminent.
What is class2 lightning arrester?
Secondary class lightning arrestors are designed to protect most homes and businesses from lightning strikes, and are required by most electrical codes, according to, Inc., an electrical power protection company.
What is the difference between a surge protector and a surge arrester?
The surge protector has the same function as a surge arrester but is used to protect domestic and consumer electrical equipment whereas the surge arrester is for large-scale protection (medium to high voltage).
What is the difference between surge arrester and lightning arrester?
Surge arrester protects the installation from inside while lightning arrester protects the equipment from outside. Surge arrester protects the system from lightning, switching, electrical faults, and other transients voltage and surges while lightning arrester is mainly used for lightning strikes and associated surges.
How do I choose a surge protective device?
Three rules of thumb for choosing surge protection Here are some rules of thumb for installing a surge protection device (SPD): Familiarize yourself with types, or categories, of SPDs. Assess the risk of lightning strikes and discharge capacities. Use the right devices to protect the surge protection itself.
What is a surge protection device?
The surge protective device (SPD) is a kind of product that protects valuable electrical and electronic equipment against transients, originating from lightning and also from switching sources. Surge protective devices are devices consisting mainly of voltage-controlled resistors (varistors, suppressor diodes) and/or spark gaps (discharge paths).
What is a type 1 component assembly?
Type 1 component assembly is a Type 4 SPD that once installed inside another piece of equipment would be tested as a Type 1 SPD (would not require external overcurrent protection).
What is SPD type 2?
SPD Type 2 devices are designed to remove all the overvoltage from supply circuits that are not likely to be directly hit by lightning. SPD Type 2 is connected downstream SPD Type 1 or SPD Type 1+2, (minimum distance 1 m) and they protect machines and tools connected to the ground and reduce the risk of economic loss.
What is UOC in electrical?
Uoc: test voltage. This is the peak value of the no-load voltage of the combined test-generator; this has a waveform of 1.2/50 μs (figure 7) and can supply at the same time current with waveform 8/20 μs
Can a single SPD protect against transients?
A single SPD also cannot fully protect against transients that enter a building along other conductors, such as grounding conductors or conductors powering loads on the roof, exterior walls, and grounds. For example, if lightning strikes the ground near a building’s grounding point, the voltage could enter into the building and damage load equipment without ever reaching the service entrance SPD. For this reason, SPDs should be installed at the service entrance, distribution panels, and critical load equipment using a cascaded approach.
What are surge protective devices?
Introduction: • The devices used to prevent damage to electronic or electrial equipments from voltage spikes or transients are known as surge protector or surge suppressor. • It is inserted in AC utility line and/or telephone line. • It is also called transient suppressor. • Surge protectors provide protection by dissipating any excess power and preventing it to reach connected equipments/devices.
Surge protective device types
Following are over voltage protection devices. Let us understand construction and functions of these surge protective device types.
