Surge Protector vs Surge Suppressor: In-Depth Comparison

It can be very confusing choosing between a surge protector and a surge suppressor. Besides, if you don’t actually tell the difference specifically.

Surge protector vs surge suppressor – what is the difference?

The surge protector shuts down the entire electric line. On the contrary, the suppressor works without shutting down. A surge protector is suited for PCs. But the suppressor is for telephone and power lines. Also, the protector can handle huge spikes. But the suppressor is suited for medium ones

Stay with me before choosing one for your electric line or device. I have made this whole article to get you out of the dilemma. 

Let’s jump to the details!

What is a Surge

You might be curious about the aims or operations of both devices. Let me first define what a “surge” is.

A surge in an electrical system is a brief increase in voltage or current. Voltage (>2000 volts) and current (>100 amperes) are their specifications.

Surge rise times typically range from 1 to 10 microseconds. I hope now you got a better idea of the surge. 

You will now easily understand the distinction between a surge suppressor and a surge protector.

Surge Protector vs Surge Suppressor: Quick Comparison 

If you’re new, starting with a full-fledged discussion may be too much for you. That’s why I’ve opted to swiftly go over the distinctions. It’s like the same dilemma of choosing one between 3 wire and 4 wire.

Besides, this makes the comparison a lot easier to understand. Here I have prepared a quick compression table for you:

CategoriesSurge Protector Surge Suppressor
Spike Temporarily shut down Control the voltage 
Usages Industries Residential, commercial
Suited device PC Telephone lines, Power lines
Capability Capable to handle huge spike Capable to handle medium spike

Still unsure about which one is best suited for you? Keep reading for a much more detailed comparison below. 

Surge Protector vs Surge Suppressor: A Detailed Discussion 

The words ‘Surge Protector’ and ‘Surge Suppressor’ might seem similar. But they are not interchangeable. 

In a sense, these phrases refer to devices that regulate excessive voltage. Yet, there are numerous differences between the two in terms of technologies. And also they required degrees of security.

Now on to the heart of the issue.

Working Principle 

A surge protector is a device that guards electrical devices against overvoltages. If given a voltage higher than its rated voltage, it can induce currents to flow. 

When there is a voltage spike or splurge that exceeds a specified level, it prevents the splurge. It accomplishes this by detecting the voltage spike. As a result, it temporarily interrupts power flow while still operating.

The other method of operation is for it to cut off the power supply. Though it shut down the line temporarily, you might be thinking surge protectors might go bad? It can exist for an extensive stretch of time before dying on its own.

In the instance of a surge, the surge protector simply shuts down the equipment. It also has a tendency to transfer the excess voltage/current from a surge. And transient into the grounded wire.

A suppressor, on the other hand, has the added benefit of controlling voltage. As well as maintaining power consistency in the case of a spike.

Surge suppressors, on the other hand, restore the voltage to normal levels. And prevent it from shooting up to a specific degree if a splurge occurs.

Field of Common Usage 

Surge protectors are primarily employed in the energy, transportation and telecommunications industries. You can also plug in a surge protector with GFCI outlets. Surge protectors are well-suited for widespread application in electronic gadgets. 

It is used by those who have access to electricity. Also, communication lines (data, fax, modem, and so on). 

It is primarily utilized with computers and telecommunications equipment. Surge suppressors are mostly employed in residential and commercial electronics.

Suited Device 

A surge protector is best utilized in conjunction with a computer. Surge protectors should be used to protect your personal pcs and televisions. A gaming system and charging phones can also be used during a storm. 

A power spike or surge can damage these devices or possibly wipe out all of your data. However, there are amperage parts in your computer. These circuits are easily broken in the event of a surge. And resulting in the loss of critical data.

This damage may limit the lifespan of the computer and delete the whole of your data. Or even cause serious harm, such as shutting down your machine. Surge protectors can also be employed with components of an entertainment center. 

The surge protector extends the life of these devices in this scenario. Surge protectors are required because a large-scale power surge can cause significant harm.

Lightning strikes have an equal likelihood of damaging telephone cables and power lines. Both can benefit from a surge suppressor.

Which One to Choose Between Surge Protector and Surge Suppressor 

You need to determine the criteria first before choosing a surge protector or suppressor. You should be choosing it based on where you want to apply it. 

If you are going to safeguard your residence or commercial space. Then a surge suppressor is recommended for you. But for safeguarding your industry from spikes, try a surge protector. 

Also if you want to protect your valuable devices from spikes. You can use a surge protector rather than a surge suppressor. If you consider buying a surge protector for safeguarding your expensive devices. 

Here are some suggestions I have gathered for you:

Product 01 
Product 02 

These surge protectors are top-notch in quality. And They are ranked depending on user feedback.


Question: Is it required to use surge suppressors?

Answer: A power spike or surge without a surge protector could decrease the life of your computer. also, wipe out all of your data, or even entirely destroy it. Any high-end electrical gadget, in fact, must be secured by a surge protector.

Question: Is a refrigerator necessary to have a surge protector?

Answer: Refrigerators are initially expensive. They will, however, might last years if treated properly. Use a surge protector to safeguard and prolong the life of your refrigerator.

Question: Is there a difference between surge arresters and lightning arrestors?

Answer: Surge arresters and lightning arrestors are not the same things. The first is installed outside, while the second is installed inside. Both, on the other hand, protect your electronic devices.

Bottom Line 

Thanks a lot for tagging with me till the very end. Hope you are clear now about what’s best between surge protector vs surge suppressor

Anyways, you may use them to protect your house or industry from the spike. You should always console with a professional and hire a professional to do the job. 

Best of luck!
