Why do I need an extension lead?

A multiple power strip is needed when you do not have enough wall sockets available or within reach. An extension lead, also known as a extension cord or power strip, provides several electrical devices with standardised plug connections with a connection to the mains. This makes it possible to flexibly supply several electrical devices with power at the same time.

What types of extension leads are there?

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.

There are different types of multiple socket outlets and brennenstuhl® offers a large selection of functionality. We will show you how to find the perfectly suitable extension lead for your needs.

Extension lead with on/off switch

Extension leads with illuminated on/off switches are available in various designs. The classic version is the extension lead with one illuminated on/off switch that supplies power to all sockets simultaneously or disconnects them from the mains. A 2-pole switch disconnects or closes the live wires.

In addition, there are extension leads with hand/foot switches. Multiple plugs with an external switch are ideal if the power strips are in hard-to-reach places, for example under the sofa or behind the cupboard. However, the switch with extra cable means that the socket outlets can still be conveniently switched.

Extension lead with individual switches

There are also extension leads with several switches to individually supply power to sockets.

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

With radio-controlled socket strips, the plugged-in devices can be conveniently controlled by remote control or app. Thanks to intelligent radio control, you can connect all the devices you want up to 3,500 W to the radio-controlled power strip and operate them from the comfort of your couch. Of course, the power strips can also be switched manually and independently of the remote control or app.

USB extension lead

Power strips with a USB charger enable to charge electronic devices such as smartphones or cameras via the USB sockets. The USB charging function for brennenstuhl® extension leads is available with a maximum total charging current of 2.1 A or 3.1 A.

Surge protected extension lead

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?

Protection against overvoltages and electromagnetic current peaks can be achieved by using surge protection extension leads, which are used between the power supply (socket) and the device. These ensure that dangerous overvoltages are diverted within fractions of a second and thus protect the devices plugged in.

What are the benefits of surge protection?

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?

The maximum surge current for surge protection extension leads indicates how much current can be discharged without destroying the protective device. The higher the value, the more smaller overvoltage peaks the extension leads with surge protection can absorb without damaging connected devices.

When do I need surge protection?

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.

Further questions about surge protection extension leads are also answered in the brennenstuhl® world of themes.

What do you have to look out for when shopping an extension lead?

In order to find the right extension lead, you can ask yourself a few questions before purchasing:

Which plugs for extension leads? Is a space-saving flat plug needed if the multiple socket is plugged in behind furniture, for example, or does a practical angled plug fit the requirements better.

What types of socket? Multiple socket strips can contain sockets for different types of plugs, for example USB chargers, Euro plugs or earthed plugs. It is important to pay attention to the increased protection against accidental contact for socket outlets.

How many sockets for multiple socket outlets? Common multiple socket outlets are 3-way, 8-way or 10-way power strips. brennenstuhl® extension leads are available with 2 or more sockets and up to 16 sockets.

How should extension leads be arranged? The socket arrangement can also be important. If you choose a 90° arrangement, for example, you can easily plug in large plugs or angled plugs without blocking other socket positions. There are also extra brennenstuhl® extension leads with an extra large distance between sockets.

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.

Cable quality for power strips? With brennenstuhl® extension leads we use a high-quality cable.

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?

Do socket outlets need increased protection against accidental contact? Of course, safety comes first and foremost, which is why increased contact protection for socket outlets is always worthwhile.

Industrial extension leads with personal protection? An PRCD serves as mobile protection against electrical accidents between the socket and the appliance. It disconnects the active conductors from the mains at lightning speed as soon as residual currents occur.

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.

IP = International Protection

4 = (first digit) Protection against solid foreign bodies

4 = (second digit Protection against water

Frequently asked questions: Extension leads

What does increased contact protection for extension leads mean?

Increased contact protection on extension leads serves as a protective mechanism on socket outlets. The contact protection used in brennenstuhl® extension leads is based on the use of plastic sliders which close the openings to the contacts of the socket.

What should I pay attention to when plugging in extension leads?

It is easy to carelessly connect different devices to a power strip without paying attention to the maximum load capacity. If you carelessly connect several devices to one extension lead without paying attention to the total power, you will quickly overload the extension lead.

How many devices can I connect to one extension lead?

That depends on the power limit of the extension lead, which is indicated on the rating plate, for example. Usually, the maximum load capacity for extension leads is about 3,500 watts. However, what sounds like a lot is quickly consumed. Three devices are enough to fully utilise the power of the extension lead.

Can a extension lead burn?

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?

In general, you must not plug in several extension leads one after the other. This is even indicated on the extension lead with a warning "do not plug in one after the other". The reason for this is the increased risk of overloading the extension lead.
