Fixed Earthing Terminals, Wall Bushings

For installation in concrete as a corrosion-free connection to the earth-termination system for protective equipotential bonding and / or functional equipotential bonding of the down conductor, e.g. to the reinforcement of buildings.
Please observe the following minimum screw lengths for the M10 and M12 double threads:
35 mm of M10 (thread length 40 mm)
15 mm of M12 (thread length 20 mm)

With M16 connection thread for higher current loads (50 Hz), e.g. for connecting the ring equipotential bonding system with the earth-termination systems of power installations with nominal AC voltages over 1 kV (transformer earthing).

For connecting the reinforcement with clamping piece.
For round conductors or fixed earthing terminals with simultaneous fixing in the formwork.

Arrangement:
(II) = parallel
(+) = cross

Connection and bridging device for using the reinforcing bars (longitudinal bars) of reinforced concrete supports or walls as a down conductor.

Screwed to the fixed earthing terminal to connect, e.g. an equipotential bonding bar or structural parts such as steel girders, etc.

For connecting round and flat conductors to fixed earthing terminals with M10 / M12 thread (e.g. Part Nos. 478 011, 478 200) and M16 thread (Part No. 478 027).
Clamps with M10 thread are also suitable for installation on the rear side of the fixed earthing terminal (without connecting shaft), e.g. to connect a flat strip.

For connection to fixed earthing terminals with M10 thread, lock nut and spring washer, for use in case of perimeter insulation or thermal insulation composite systems.

With MV clamp made of StSt (V4A) for round conductors 8–10 mm.
Water-pressure-tight wall bushing for leading earthing conductors / equipotential bonding conductors through brickwork or walls; with M10 threaded rod made of StSt.
For subsequent installation through borehole (Ø14 mm) or through spacer in the formwork.
Test for water pressure-tightness up to 1 bar features an installation depth of 10 m in stagnant water.

For installation in the formwork.
Is suitable for water-pressure-tight wall bushings; e.g. for connecting the ring earth electrode with the equipotential bonding bar or the equipotential bonding conductor in the foundation.

Sealing collar for bushings in case of watertight foundation slabs / walls (e.g. white tank).
Water-pressure-tight for pushing on round / flat conductors with StSt tensioning straps.

Pressurised water test up to 1 bar represents an installation depth of 10 m in stagnant water, additionally tested with 5 bar compressed air according to EN 62561-5.
