Joule rating

1,000 to 2,000 joules: For appliances that you want to keep safe and working properly, look for a joule rating in the 1,000 to 2,000 range or higher. Cellphones, tablets, routers and laptops should be protected in this range, but it would still be safer to find a higher joule rating.

How many joules do I need to protect my TV?

A common question we hear is, how many Joules do I need to protect my TV? For HDTVs it is best to consider the highest Joule ratings – at least 2000. Austere recommends the V Series Power (3000 Joules) for 4K HDTVs less than $1,500 and VII Series Power (4000 Joules) for 4K HDTVs more than $1,500 and 8K HDTVs.

Is a higher joule rating better?

Energy absorption/dissipation: This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.

Is 600 joules protection enough?

Generally, you'll want to look for point-of-use surge protectors rated for at least 200-400 joules, but 600+ joules is even better. Surge protectors rated for 1000+ joules are optimal for protecting electrical devices like lamps, small kitchen appliances, digital clocks, etc.

Is 1500 joules good for a surge protector?

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 many joules is a good surge protector?

1,000 to 2,000 Joules If you're trying to protect things like cell phones, basic laptops, printers, routers, and copiers, you'll want a surge protector with a rating between 1,000 and 2,000 joules. This rating is also large enough for your power tools and other building appliances.

Is it better to plug TV into wall or surge protector?

How many joules do I need to protect my refrigerator?

Ideally, a surge protector which provides a 1000 to 2000 joule rating will provide the required protection. Yet, some high-power surge protectors also provide a joule rating of more than 2000. For example, a home refrigerator has 200 W of average power multiplying it by five, we get 1000W.

How many joules is a lightning strike?

With an average bolt of lightning striking from cloud to ground containing roughly one billion (1,000,000,000) joules of energy, that is a lot of power in every lightning bolt!

How many joules do I need to protect my computer?

2,000+ joules: Surge suppressors with over 2,000 joules of protection should be considered for your most important, and expensive, devices, such as computers, home theaters, gaming consoles and more.

Which surge protector should I buy?

Choose a surge protector with a joule rating at the very least in the 200 to 400 range. Sensitive or costly equipment, such as computers, displays and audio/video equipment, warrants a joule rating of at least 1000. A joule rating over 2000 indicates maximum protection.

Is it better to have higher or lower joules?

Joules are the key to surge protection. With surge protection, it's about joules. The joule rating of your surge protector determines how much energy your surge protector can absorb. The higher the joule rating, the greater the protection.

1 joules to volts	1 coulombs	1 volts
2 joules to volts	2 coulombs	1 volts
6 joules to volts	3 coulombs	2 volts
120 joules to volts	4 coulombs	30 volts

How many hits can a surge protector take?

Know your joules For example, if a device has at least 1,000 joules of protection, the surge protector can guard devices from a single 1,000 joule power surge hit or 10 separate 100 joule hits.

How do I know what size surge protector I need?

The formula to determine this will depend on the type of system. For example, for a single-phase system (also called a split-phase system), the line-to-line voltage is divided by two. The result is the optimal amount of volts that the SPD should have for that system.

Will a power surge damage my TV?

A power surge can damage a TV. The damage can be minimal, such as a single HDMI port no longer working, or it's possible that it could be completely fried and no longer able to operate. A surge protector is a simple device that will add a layer of protection to any devices connected to it.
