Multi plug extension cord 4x >>STL4

• shielded socket strip for shielding low-frequency electrical fields and reducing alternating magnetic fields
• two-pole disconnection of the four socket inserts
• incl. child safety lock and decoupling filter
  

The shielded socket strip STL4 is a very high-quality processed socket strip for the reduction of low-frequency electrical alternating fields and energy consumption.  

The shielded socket strip STL4 is preferably used for 2-pole disconnection and for operating several devices. This means that even if the plug is turned
180 ° in the socket, the voltage is always switched off.

A special advantage when using the STL4 socket strip is the 2-pole disconnection. This guarantees smooth operation of all automatic field disconnectors, such as the devices of the NA-16 series.

The 2-pole switch and child protection add safety aspects to the shielding effect.

Use of socket strips with 2-pole switch:

By using switchable power strips, several devices can be connected together (PC, hi-fi systems, etc.) and disconnected from the mains conveniently and together at the flick of a switch. If there is a need for continuous power for devices with programmed data or necessary accessibility (e.g. fax, telephone system, video recorder), you can use socket strips with combined switchable and non-switchable inserts like STL6PC. If your strip is additionally shielded, the alternating electric field is minimised to below 1-2 volts/metre (V/m) - the recommended guideline value of building biology is max. 10 V/m.

Note: DIN VDE 0100 Part 420 Para. 4.1 (fire hazard in electrical installations) must be particularly observed during use. If the total resistance of the individual plug-in connections exceeds the impedance required for short-circuit protection, it will no longer trip (VDE 0100-410:2007-06, for example, requires short switch-off times of 0.4 s for the TN system). In such cases, the temperature of the pipe can rise to the point of creating a fire source.

Therefore, the following applies (to all socket strips, whether shielded or unshielded):

do not insert one after the other

do not operate covered
