How to Choose a Surge Protection Device: The Ultimate Guide

Selecting a Surge Protection Device: Tips & Steps

The appliances we employ at home and in business industries like televisions, computers, Refrigerators, and HVAC systems require a constant flow of electricity. The appliances also get damaged in case of power surges. Lightning bolts, changes in electric power usage, inadequately wired circuits, and many other factors can cause damage to the sensitive equipment that we own due to power surges. This is where surge protection devices are implemented. In this article, we will discuss how to choose a surge protection device and the most important factors in SPDs, and the role they play in our lives.

Surge Protection Device (SPDs) Overview

SPDs eliminate the risk posed to electrical devices in the case of voltage spikes. These voltage spikes can occur at any time, during switching of electric circuits, lightning bolts, or even power outages. SPDs work by intercepting excessive voltage by grounding the excess voltage, ensuring that your electric equipment only receives voltage at safe levels.

Important Elements to Consider When Selecting Your SPD

1. Clamping Voltage

Another name for clamping voltage is let-through voltage. This describes the voltage level at which the SPD will start redirecting excess voltage to the ground. Protection is better when the let-through voltage is lower. For example, a clamping voltage of 330V is good for 120V AC devices.

2. Joule Rating

The energy absorption capacity of an SPD is measured using the joule rating. A higher joules rating indicates that the device is capable of absorbing more energy before collapsing device failure. Surge protectors with a rating of 1000 joules or greater are recommended for residential use.

3. Response Time

Response time describes the level of change in a device due to a surge.. A lower value for response time further ensures that the device will be protected instantaneously. Most modern SPDs possess response times lower than a nanosecond.

4. Maximum Continuous Operating Voltage (MCOV)

The SPD may continuously sustain up to a certain voltage without degrading, and that value is defined as the MCOV. To protect and have the best performance, it is important to choose an SPD that has an MCOV rating equal to the voltage. 

5. Nominal Discharge Current (In) and Maximum Surge Current (Imax)

•          In: Defines what the SPD can take when a surge continuously happens

• Imax: Denotes the maximum value of the ‘surge’ that the apparatus may endure once.

For home use, a surge protective device (SPD) with a rating of In 5 kA and Imax 20 kA is considered adequate.

Part Classification of Surge Protection Devices

1. Whole House Surge Protectors

These devices safeguard the entire household and all the appliances within it against surges from outside, such as lightning strikes; they are fitted at the main electrical panel.

2. Point-of-Use Surge Protectors

They are sometimes referred to as power strips. These are capable of surge protection and are perfect for individual devices such as computers, televisions, and gaming consoles.

3. DIN Rail Surge Protectors

Used mainly in industrial environments, these SPDs mounted on DIN rails serve to protect equipment within control panel enclosures.

Additional Features to Look for: Surge Protection Device

• EMI/RFI Filtering:

This reduces the level of interference caused by electromagnetic and radio waves to sensitive equipment, creating clearer power.

• USB Ports:

 Handy for charging mobile phones and tablets without using additional sockets.

• Lights:

These perform important functions of providing the operational status of the SPD and notifying when the system protection is disabled.

Installation Tips

• Proper Grounding:

 Add adequate grounding to the SPD so that it can operate efficiently.

• Regular Inspection Controls:

  Remove the SPD and check it at intervals for signs of wear or damage.

•Replace When Necessary:

SPDs malfunction and provide inadequate protection after prolonged use. Replace them when they no longer serve their purpose.
