<p>Surge protection devices help to protect devices and equipment against changes in the electrical current running through the system. Current spikes or transients can cause significant damage to equipment and is also a safety hazard. You can learn more in our <a href="/web/content/discovery/ideas-and-advice/surge-protection-guide">guide to industrial surge protection</a>.</p><h2>What are surge protection devices used for?</h2><p>Surge protection devices involve the use of surge suppressors or protectors and surge arresters.</p><p><strong>Suppressors</strong> protect equipment from voltage spikes. They block or short to ground the current in, for instance, power distribution panels, process control systems and heavy industrial systems.</p><p><strong>Arresters</strong> protect machinery from external occurrences that cause over-voltage transients like lightning strikes or switching events. These are installed in power transmission and distribution systems.</p><h2>Types of surge protection devices</h2><p>Four primary types of industrial surge protection exist:</p><ul><li>Secondary surge arresters fixed to the line side of the service panel to protect against current surges from lightning or switching events.</li><li>Branch surge panels are fixed to the load side of the main service entrance and offer protection against motor driven and internally generated surges.</li><li>Power strips protect sensitive electronics with lower voltage and ampere capabilities by blocking current spikes.</li><li>Surge protection modules provide point-of-use protection by protecting against overvoltage and current spikes.</li></ul>

Industrial surge protectors balance electrical flow and block or short current surges and voltage spikes into the earth to protect the system.

<p>Surge arresters are a type of surge protection device, used to protect machinery and equipment from over-voltage caused by things such as lightning strikes or switching events.</p><h2>Where are Surge Arresters used?</h2><p>Surge arresters are used in a wide range of power transmission and distribution systems. These surge protection devices are available in a wide range of sizes and profiles.</p><h2>How do Surge Arresters work?</h2><p>Surge arresters allow normal voltage to continue along a path, whilst diverting extra or over voltage into an earth wire. This prevents it from flowing through the electrical device causing over-voltage.</p>

Eaton SPDs - Surge Protection Devices | RS

<p>Don't let voltage spikes or surges in your power supply spark disaster for your electronic devices and equipment, protect them with a surge protection device (SPD) from Eaton.</p><p>Excess voltage in your electrical circuits can cause damage to connected devices and can also pose a serious safety hazard through the risk of causing electrical fires. An SPD is a great way to minimise those risks. How does an SPD work? Well, this type of protective device works by simply diverting excess voltage away when it's detected, usually routing it to the ground or to a neutral wire. They do this by acting as a low-resistance path for the current to follow. This reduces the amount of voltage that your other devices experience, saving the day.</p><p>As global power management experts you can rely on Eaton's SPDs to safeguard your electronic equipment in the face of troublesome transients. Their offer here at RS includes both surge arrester type SPDs and surge protector type SPDs. You'll find surge protectors used to protect individual devices, installed at the point of use. Surge arresters may be used to protect entire electrical systems, or specific equipment. They are installed at the point of entry or within the electrical system to intercept high-energy surges.</p><p>Eaton's popular FAZ range of SPDs includes handy features and benefits such as: red/green indicator lights for contact positioning, simple installation, safe operation with six levels of thermal magnetic overcurrent protection, and trip-free design.</p>

A surge protection device (SPD) helps to protect various electrical equipment and devices from changes in the current, like voltage spikes, which can cause damage and be a potential safety hazard. If you are looking to deter these electrical spikes or surges, then ABB SPD's have got you covered. ABB are a global technology company who specialise in electrification and industrial automation and can help you achieve industrial surge protection. They provide a wide variety of products for electrical distribution, protection, and control solutions. Whether your application is in an industrial, commercial, or residential setting, you can efficiently and safely distribute your electricity with ABB SPD's.<h2>What are SPD's used for?</h2>To protect your electrical devices from voltage surges or spikes, surge arrestors and surge protectors can be used. The two types of SPD are similar, but they do have some differences:<ul><li>Surge Protector: A surge protector, also referred to as a surge suppressor, is designed to protect electronic devices from smaller and more frequent voltage spikes. Many factors can cause these spikes, like switching electrical loads or power grid fluctuations. A surge protector limits the voltage to a safe level by absorbing the excess energy through its suppression components. ABB surge protectors can be used to provide localised protection through outlets or with individual electronic devices.</li><li>Surge Arrestor: Surge arrestors, also referred to as lightning arrester or a surge diverter, diverts high-voltage surges away from electrical systems that are too sensitive to withstand the high voltage currents. These high-voltage surges can be caused by lightning strikes, for example, and the surge arrestor would be able to effectively redirect the voltage to the ground, preventing damage. To instal a surge arrestor, they tend to be located where the power enters the facility.</li></ul>Both ABB surge protectors and ABB surge arrestors play crucial roles in electrical surge protection to prevent the potential harmful effects of power surges.
