DEHN välikappale 290002 DIN 48833 A 280 mm salamasuojaukseen

Installers of external lightning protection systems use the DEHN 290002 spacer to maintain a fixed separation distance of 280 mm between round conductors and the structure. The spacer is made of UV-stabilized polyamide and is suitable for conductor diameters from 8 to 10 mm. It is screwed onto the mounting surface via a 10.5 mm hole for an M10 screw.

Key specifications

• Distance to structure: 280 mm
• Conductor diameter range: 8–10 mm
• Material: UV-stabilized polyamide (PA)
• Mounting: screw mounting, hole diameter 10.5 mm (M10)
• Colour: light grey (RAL 7035)
• Operating temperature: -50 to +100 °C
• Standard: DIN EN 62561-1 (VDE 0185-561-1)

Why choose it

The spacer is weather-resistant, UV-resistant, and self-extinguishing. Its high impact and corrosion resistance ensure long-term reliability in outdoor installations.

Ideal use cases

• External lightning protection systems
• Securing round conductors on facades and roofs
• Installations requiring a 280 mm separation distance

Good to know

The spacer is insulating and designed for use with round conductors only. It is not suitable for flat conductors.
