What does VPR mean on a surge protector?
Voltage Protection Rating
Voltage Protection Rating (VPR): A rating per UL 1449 4th Edition, signifying the rounded-up average measured limiting voltage of an SPD (Surge Protection Device) when the SPD is subjected to the surge produced by a 6 kV, 3 kA 8/20 µs combination waveform generator.
What is VPR voltage?
VPR is the maximum voltage allowed to pass through the surge protector during a spike. It’s the voltage level which causes the MOV to “clamp” down on the spike to prevent most of the surge from passing through to connected equipment.
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.
Should I use a surge protector for my washing machine?
A general rule of thumb is to not use surge protectors for high-powered appliances such as your washing machine. It’s also advised to not connect multiple surge protectors together. It may seem like a handy way to get more outlets but all it is, is an electrical fire hazard.
What is surge protection Type 3?
Type 3 Surge protector device (SPD) Type-3 SPD is characterized by a combination of voltage waves (1.2/50 µs) and current waves (8/20 µs). • Its main function is to limit low level surges which can damage sensitive electronic circuits in TVs, PCs and electric appliances.
Is 2100 joules good?
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…
Should you use a surge protector with a refrigerator?
Small, cheap appliances like lamps, can be plugged directly into the wall. But bigger or more important items, as well as appliances that require constant power, such as computers, printers, televisions, and refrigerators, should all use surge protectors.
