brennenstuhl® offers extension leads for almost every application. From the common 3-way power strip to the sophisticated high-tech extension lead with surge protection, automatic function and other intelligent features, brennenstuhl® extension leads meet the most diverse requirements. brennenstuhl® power strips are available with illuminated on/off switch, increased touch protection, with USB charger, surge protection, main-follow function and many other features.

The 3-way brennenstuhl®Connect Ecolor WiFi extension lead has also been awarded the iF DESIGN AWARD 2020.Master-slave extension leads are also available from brennenstuhl® - brennenstuhl® designates the technology Main-Follow. 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? A further word of warning: the maximum power handling of longer extension cables, such as cable reels designed for indoor or outdoor use, depends on the cable being completely unwound. If you’re planning on using high powered electric garden tools, then the cable must be unwound to prevent excessive heat build up in the cable reel. Where a wound cable reel might only handle 1,000 watts (1KW), the same reel may be rated at around 3,300 watts (3.3KW) when the cable is unwound to its full length. And similarly, don’t be tempted to tightly wind up a standard extension cable in the name of neatness if you’re going to be using it with power hungry appliances – items with a high power draw can cause the cable to heat up dramatically and create a fire hazard. Following on from this, it is also important to make sure you are purchasing an Extension Lead with properly insulated connectors and plugs.

Individually switchable extension leads enable electrical appliances to be switched on and off individually without interrupting the complete power supply of the other electrical appliances plugged in. Wireless extension leads Further questions about surge protection extension leadsare also answered in the brennenstuhl® world of themes. IP protection class for extension leads?The IP44 protection rating indicates that the device is protected against foreign bodies and splashing water and that the extension lead is therefore suitable for outdoor use.Extension leads can provide protection against various types of leakage currents. These can occur due to lightning strikes or overvoltages. The protection is limited to a certain amperage in each case. The higher the selected amperage, the higher the maximum surge protection offered by the extension lead. What are surges?

Surges are all overvoltages that exceed the limit value of the mains voltage for a short time. Without effective surge protection, the overvoltages destroy sensitive electronic components in the circuits of the connected devices. What does surge protection mean for extension leads? 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. What additional functions does my extension lead need? Are switches needed? Do appearance and design play an important role? Is a higher IP protection class required for outdoor use? Is surge protection worthwhile?brennenstuhl® has high-quality extension leads with 19" or 10" format. These extension leads for control cabinet technology in industrial quality are suitable for installation in network or server cabinets where the inch format is used. There are many types of Extension Leads on the market, but there are some rules that every trader should follow when it comes to Extension Lead safety.

It is never recommended to plug one Extension Lead in to another, as this increases resistance and the risk of overheating and causing a fire.We have worked out some examples of the appliances you can plug in to an Extension Lead in various commercial and domestic scenarios, without overloading. By our calculations, you can comfortable fit all of these commercial/office appliances in to one Extension Lead without overloading it: How long must the extension lead cable be? To ensure that the extension lead is long enough for every application, there are power strips with different cable lengths from 1.5m or 3m up to 5m.
