<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 complete <a href="https://uk.rs-online.com/web/generalDisplay.html?id=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>

<p>Surge protectors (also referred to as surge suppressors) help to protect equipment from voltage spikes. Surge protectors work by blocking or shorting to ground the current in, for instance, power distribution panels, process control systems and heavy industrial systems.</p><h2>Where are surge protectors used?</h2><p>Surge protectors are features in a wide range of domestic and industrial settings, providing a safe way for over-current to be grounded internally. Surge protectors can be found in a variety of electrical devices found around the home or office.</p><h2>Why use a surge protector?</h2><p>Surge protectors help to protect your electrical devices from brief power surges. Power surges can be caused by a wide range of things including lightning storms, power outages, faulty wiring and more. Utilising a surge protector will ensure than any power surge generated will be blocked, helping to protect your electrical device.</p>
