Application Notes

A significant share of low-frequency electric fields comes from the building's own wiring. A mains disconnect switch (demand switch) automatically de-energises a circuit when no load is present — for example, the bedroom circuit switches off completely while you sleep. Shielded power strips reduce the fields emitted by the device cables on your desk.

Application Areas

Automatic overnight mains disconnection on bedroom circuits (NA7)
Reducing cable-borne fields at desks and in studios
Keeping children's-room socket circuits voltage-free
Clean lines and field reduction in audio/video systems
Lowering low-frequency exposure without rewiring

Installation and Application

The NA7 demand switch is installed by a licensed electrician in the fuse box, at the head of the circuit to be protected.
No device drawing standby current (chargers, clocks) should remain on the circuit; otherwise the line stays live. A control lamp is used if needed.
D-series shielded power strips plug into an earthed socket; the shielding effect requires the building's earthing to be sound.
The power strip can be fixed under the desk with the D6867 bracket.

Care and Service Life

The electrical products need no maintenance. That the NA7 is working correctly and the line stays voltage-free at night can be verified once a year with a simple voltage tester. If a fault is suspected, the work should be done by your electrician.

Frequently Asked Questions

Does the demand switch also turn off the refrigerator?

No — it only manages the circuit it is connected to. Always-on appliances like the refrigerator stay on a separate circuit; the typical use is the bedroom socket/lighting circuit.

What happens when I switch on the light?

The NA7 senses the load demand within milliseconds and energizes the line instantly; the user notices nothing. When consumption stops, the line goes voltage-free again.

What does a shielded power strip solve?

With its metal body and shielded cable, it markedly reduces the low-frequency electric fields radiated by the extension and device cables under your desk; it makes a particular difference for exposure around the feet and knees.
