Weidmüller has launched its new JB 25–50 and EBB 25–50/16 potential equalisation blocks for decentralised potential equalisation. These allow a ring line of 25 mm2 to 50 mm² to be installed, which merges all the potentials present in production lines. Branch lines of 16 mm² can be produced from the ring line. The easy-to-install terminal blocks reliably equalise differences in potential.
To avoid undefined currents in systems, long production lines need one standard potential equalisation. Three-part lightning conductor terminals are usually used. However, these can be cumbersome and can only be assembled in the cable conduit with a great deal of time and effort. However, the new potential equalisation terminals can be installed with ease and are a low-cost solution for reliably equalising potential, for example in the automotive industry, with its long production lines.
The potential equalisation blocks prevent undefined currents, which may cause errors and faults. Compared with star wiring, the decentralised potential equalisation offers huge potential savings. It doesn't require long conductor lengths to be routed from the individual field components to the busbar, just short branch lines to the terminal block on the ring line. Less space is thereby taken up in the cable conduit and the wiring times are reduced considerably.
The new JB 25–50 and EBB 25–50/16 potential equalisation blocks have an ergonomic design and a clever construction, and they can be quickly installed in the assembly duct with ease. Users achieve the desired potential equalisation in no time and installation isn't expensive. Furthermore, the potential equalisation blocks from Weidmüller take up little space in the cable conduit and with an installation height of just 24 mm leave sufficient space for data and power lines. JB 25–50 and EBB 25–50/16 are also quick to install because all clamping screws on the potential equalisation blocks have the same distance across flats. No tool changes are therefore required during the installation process.
The EBB 25–50/16 potential equalisation block integrates the option for connecting two branch lines for 16mm² conductors ex factory. Weidmüller also uses light-coloured screws in its new potential equalisation blocks, which stand out clearly in dark environments.
