Waarom is trekontlasting nodig?

Zonder trekontlasting komen trek, gewicht en trillingen van de kabel direct op de aansluiting. Dat leidt tot loszittende verbindingen en storingen.

EN 62444 stelt eisen aan kabelinvoer en trekontlasting van kabels in elektrische installaties. De AP-modules en kabelkammen helpen daaraan te voldoen.

Wat is het verschil tussen messing en aluminium busjes?

Beide geven een stevige bevestiging van de kam. De keuze hangt af van de toepassing en de gewenste uitvoering; wij adviseren graag.

Kan ik trekontlasting en EMC combineren?

Ja. Veel EMC-klemmen geven zelf ook trekontlasting via kabelbinders. Voor de orde in de kast combineer je ze met modules of kabelkammen.

Strain relief.No pull on the connection.

A cable that hangs on its clamp will come loose sooner or later. Strain relief modules and cable combs fix cables before they reach the terminal, arrange them neatly in the cabinet and help you comply with EN 62444.

About the product group · Detas Ultra

Strain relief

Standard: Strain relief to EN 62444
Material: PA66
Version: Modules and cable combs in several lengths
Mounting: With brass or aluminium bushes too

The AP modules and cable combs are mounted in the cabinet or panel. Cables are laid in the comb and secured with cable ties. This way pull and vibration are absorbed by the module and not by the terminal strip.

There are versions in different lengths, wireless modules (AP-DP) and cable combs with brass or aluminium bushes for a firm fixing. The material is PA66.

When

When do you choose strain relief?

01Cables come from below or above: The weight and pull of the cable must not rest on the clamps.
02Vibrating machines: Secured cables do not chafe and do not vibrate loose.
03Order in the cabinet: Cables neatly side by side per group: faster fault finding, easier extension.
04Standards: Demonstrably meets the strain relief requirements of EN 62444.

01Count the cables per row
The number and diameter determine the length of the module or comb.
02Choose the mounting type
Standard module, wireless AP-DP or a comb with brass or aluminium bushes.
03Combine with EMC
Shielded cables? Combine strain relief with an EMC clamp for the shielding.
04Think about the entry
Strain relief works best together with a suitable cable entry in the cabinet wall.
