Design: Dummy module insert for installation in the VLTM mounting rail in combination with VLGF device carriers. Additional VLMF module made of extruded aluminum profile, powder-coated in white, silver (-SI) or black (-SW). Spring steel clamps for fastening to the mounting rail. The VLMF modules can be placed variably between the VLGF device carriers. Electrical adapter for automatic tapping of the protective conductor in the mounting rail. Color and optical coding (green) for easy installation. Mechanical coding to prevent incorrect installation (anti-twist protection).
