The AM11 earthing terminal is used, for example, for the potential equalization of air-conditioning and ventilation ducts. The earthing terminal has a single >10 mm² Cu terminal. The terminal bar is made of tinned copper. It is affixed with two pull rivets (pop-rivets), Ø 3,2 mm, in the air-conditioning or ventilation duct and the protective lead is connected to the connector attachment point. The conductors having a cross-section of Cu 1,5 - 10 mm² are suited to a conductor connector equipped with conductor protection.

The potential earthing bar AM5 is intended for the connection of system earthing conductors in buildings. Into AM5 it is possible to connect 5 pcs max. 50 mm? conductors. The bar is made of tinned copper and fitted with zinc-plated steel screws and tracking-resistant thermoplastic spacers.

The earthing terminal AM8 is mainly used for connecting the earthing conductors to various pipework in sizes Ø 8 - 28 mm. It is possible to adjust the terminal to suit to four different pipe thicknesses. The terminal has two 35 mm² pillar terminals. The conductor bar is made of tinned copper and the strap of zinc-plated steel. The pillar terminals are of zinc-plated and yellow passivated steel.

The earthing conductors, max. 35 mm² Cu, are connected to the various pipework using an earthing strap PP36 with a strap clamp AM2 and terminal AM3. In case a 50 mm² or 70 mm² Cu-conductor is connected to the earthing block, both ends of the earthing strap must be pressed together with the terminal to get sufficient conductivity. The terminal and the strap clamp are of zinc-plated and yellow passivated steel. The 6 mm screws are tightened with a 10 mm wrench. The earthing strap is made of tinned annealed copper 1,5 mm thick.

The earthing terminal AM9 is mainly used to connect earthing conductors to various kinds of pipework, in sizes Ø 6-15 mm. The earthing terminal can also be used to connect earthing conductors to a building’s concrete reinforcement. A suitable concrete reinforcement bar has a diameter of between 8-15 mm. The earthing conductor has one 4-35 mm² strap. If there is a need for a 25 mm² copper connector, two AM9 terminals must be used in parallel. The conductor bar is made of tinned copper and the strap is made of zinc-plated, yellow-passivated steel.

The potential equalizer bar AM4 is intended for the connection of system earthing conductors in buildings. Into AM4 it is possible to connect 8 pcs max. 50 mm? and 2 pcs max. 70 mm? conductors. The bar is made of tinned copper and fitted with zinc-plated steel screws and tracking-resistant thermoplastic spacers.
