Demand switch NA7 comfort | LED tester and x21 mains filter included

Demand switch NA7 comfort with LED tester and x21 mains filter. This is probably the best-selling GIGAHERTZ mains isolator with the VDE mark and 16 A load capacity

  • Reliable function also with rotary dimmers, fluorescent and energy-saving lamps, halogen spotlights and devices with start-up electronics such as vacuum cleaners, etc.
  • Orientation lights in light switches and baby night lights also work when they are disconnected.
  • Reverse polarity and overvoltage protection.
  • LED display for the switching status “disconnected”.
  • VDE mark

That is how the GIGAHERTZ NA7 comfort demand switch works

The line supply produces magnetic and electric alternating fields. While the magnetic fields “disappear” when the consumer is switched off, the electric fields remain in the whole power supply system. This is where the mains decoupler comes in: it is installed into the fuse box and automatically separates the circuit it is intended for from the network as soon as the last consumer is switched off. As soon as a consumer is turned back on, the mains decoupler recognizes this and automatically turns the supply voltage back on without any delay. You do not notice the mains decoupler in day-to-day life.

Technical details about the GIGAHERTZ NA7 comfort

  • Nominal voltage / load capacity: 16 A, 230 VAC / – 10%, 2300 watt incandescent lamp load.
  • Mechanical service life of the relay: approx. 15,000,000 switching cycles.
  • 1-pole disconnection: for optimal personal protection and minimal residual ripple.
  • Residual ripple: <2 mV / <4 mV / <8 mV (nominal / typical / maximum).

x21 mains filter for dirty electricity – this demand switch’s feature

Installing the provided x21 mains filter with the demand switch strongly lowers the stress caused by dirty electricity.

  • The mains filter dampens voltage peaks from the power supply (“dirty power”), improves the EMV properties of mains decouplers and increases their switch stability.
  • This is an additional measure to improve the quality of the network through the circuit being protected by the mains decoupler, which is effective regardless of the make and switch status of the mains decoupler.

Normally, you would need many individual plugs, one per socket. However, by installing the filter to the demand switch, the whole connected circuit is filtered. A reduction to under 50 GS makes a difference, but getting to under 25 GS units is ideal.

LED control lights to easily check the demand switch

The provided LED control light helps you comfortably check that things are switched off in the room. This stays plugged in a visible for the whole day. If the LED lights up, the mains decoupler has switched the circuit off. If the “Light OFF” display still shows, a permanent consumer on the same circuit is stopping it from switching off.

    Quick delivery. Good packaging. Easy to install in the fuse box (instructions came with it). I installed 3 in the fuse box. LED lights are recognized. Socket strips with foot switches (relay) are not, unfortunately.

    Quick delivery, good packaging.
    It is well made. Installation was easy, good description.
    Works perfectly. It even recognizes LED lights.
    After decoupling the phase, 230 volts of direct current remained as control voltage.
