Product Information

Metal Oxide Varistors are the most important electronic components inside Surge Protectors that perform the “magic” filtering of excess voltage. They have a limited lifespan. (Image credit: Tripp Lite)

This lead not only allows you to extend the reach of your home devices, but you can also power them on and off remotely.There are various reasons why a surge protection product is worthwhile. The financial damage and annoyance is great afterwards when expensive electrical appliances such as televisions, computers or kitchen machines are damaged by lightning strikes and surges. To avoid these surges, a surge protector can reduce voltage peaks to a level that is not dangerous for the end device. How much surge protection is needed? When an extension lead is overloaded, it can heat up enormously.This can cause a "smouldering fire". A smouldering fire means that there are no visible flames at first. This makes it all the more dangerous because it is not easy to detect.Dust or other flammable materials can then cause a flame fire to start and spread until the surrounding area catches fire. Can extension leads be plugged in one after the other?

Extension leads themselves do not consume electricity when they are not in use. They are essentially passive devices that provide a means to distribute electricity from a power source to multiple devices. Further questions about surge protection extension leadsare also answered in the brennenstuhl® world of themes. The most dangerous causes are very high voltage peaks triggered by indirect lightning. Power surges also enter the power grid through indirect lightning in enormous current strengths or reach computer systems, video and hi-fi equipment via the telephone and antenna lines and destroy these devices without appropriate protection. If you want to protect your electrical devices from damage or destruction by high voltage peaks, it is better to connect them to an extension lead with surge protection.

Industry standards for surge suppression and power conditioning devices include IEEE 62.41 and UL1449, which limit the quantity of electricity that can pass through them. They specify how the surge suppressors will handle surges and what voltage they will clamp at. UL1449 specifies 330V as the best clamping rating for Metal Oxide Varistors (MOVs). However, not all surge protector manufacturers use the same clamp voltage ,many use 400 volts. If your equipment is more critical or sensitive, you want to choose a surge protector with a lower clamp voltage. In the latest edition 3 specification, the term "Voltage Protection Rating" or VPR is used instead of let-through or clamping voltage. If a lead doesn’t have this you should really avoid it as it will be unsafe to use as you won’t know what its energy capacity will be when you’re plugging devices into it. Are extension leads safe? For the technically inclined who want to know: it’s small electronic components called Metal Oxide Varistors, or MOVs for short, which are more often used for this filtering of surges. Other types of filters are gas discharge arrestors which are often seen in antenna protectors, but most of the time, MOVs are used, often in combination with other components like capacitors.

Get access to a total of 12 AC outlets and five USB Type-A ports with this power strip from Auopro, which boasts an octagonal prism shape, four sides of which house the outlets. It's an extremely effective design that keeps things compact while allowing you to plug all your devices and then some. And it's just the thing a small team needs. Max Amp: 15 amps | Wire Gauge: 12 gauge | Wattage: 1,875 watts | Voltage: 125 volts | Available Lengths: 50, 100-foot | Warranty: Limited LifetimeThis type of brennenstuhl® extension lead in a practical, square shape allows access to the power source from all sides. Placed centrally on the table, this is a practical feature especially when a partner, family member or colleague is still at the table together.

For a heavy-duty, ready-for-anything extension cord, you can’t go wrong with the Iron Forge Cable. It offers a wide range of lengths from three to 100 feet and has the biggest wire gauge on our list at ten, so you get higher amperage and wattage at 15 amps and 1,875 watts, respectively. That ensures consistent power, even throughout big projects with seriously beefy power tools like saws, compressors, and generators. Though we technically have surge protectors on this best extension cord guide, there are some major differences between the two.When not in use, make sure to unplug all devices from the extension lead or cable reel. Leaving the devices plugged in can cause the lead or reel to overheat, which can lead to fire hazards. Shopping for an extension cord isn’t the most complex task, but there are still a few things to keep in mind to find one that matches your needs. Power strips with a USB charger offer the possibility of charging end devices such as smartphones, tablets, cameras and many more directly at the power strip with USB charger. This stands for Ingress Protection and as a rule of thumb if you’re looking for a waterproof extension lead it has to be at least IP54 rated so that it’s watertight. Anything higher than this will have even more protection. Do extension leads need surge protection?
