Terminal block accessories

Unlike the standard FBS plug-in bridges, the reducing bridges connect terminal blocks with two different nominal cross-sections. This means that feed-ins and group connections can be implemented quickly and easily.

The potential bridges are suitable for vertical level bridging of double-level or multi-level terminal blocks. Using the example of a double-level terminal block (PTTB 2,5), the lower and upper levels can therefore be connected. NOTE: The double-level terminal blocks with the ...PV already have a permanently integrated potential bridge, which means that a PV bridge is not required.

The SB-ME bridge bars have been developed for the testing tasks of transformer terminal blocks. The bridges can be adjusted by means of a slider, which means that the bridges can either connect the potentials or not. The bridges can remain plugged in during this time. To prevent unintentional actuation, the slider can be secured by means of two screws.

The FBSH short-circuit plugs are similar to the FBS plug-in bridges. They also combine two potentials, but are not designed for permanent retention. Unlike the FBS bridges, the short-circuit plugs have an extraction tool that enables the plugs to be inserted and removed more easily. In addition, the FBSH plugs have a different plug-in mechanism, which makes it easier to remove the plugs from the function slot.

The PAI test adapters are designed for the function slot of the terminal blocks. The test adapters are designed such that they can permanently remain in the terminal blocks. The test plug is simply inserted into the adapter to perform a test.

The alignable test plugs can be combined to create individual test probe blocks. The plugs can be easily plugged together. Spacer plates are available to skip individual terminal blocks when using the test probe blocks. The spacer plates can be connected to the test plugs in the same way.

The LPS service plugs are suitable for service and test purposes in the test field. They make contact in the function slot and can be repeatedly plugged in and unplugged. In order to achieve high insertion cycles while providing a consistent and long-lasting level of quality, the contact surfaces are silver-plated. The connectors are available as single or modular alignable versions. The connectors are equipped with LP lever technology to ensure easy handling when connecting all conductor types.

The P-DI isolating plugs are suitable for the easy separation of signals. Unlike knife disconnect terminal blocks, the isolating plugs can be easily plugged in and removed by hand. To ensure that the isolating plugs are not lost, the plugs can also be plugged into the disconnect zone the wrong way round. In this case, the current flow remains interrupted.

The feed-through connectors and feed-through barriers enable the permanent transformation of basic disconnect terminal blocks. Feed-through connectors convert the basic disconnect terminal block into a normal feed-through terminal block and the feed-through barrier permanently interrupts the current flow between the two connections.

The fuse plugs enable easy integration of a fuse into the basic disconnect terminal blocks. When selecting the fuse plug, you can choose between different versions with and without LED display. The choice of LED display also defines the voltage.

In addition to isolating plugs and fuse plugs, the portfolio of function plugs also includes component connectors. As with the fuse plugs, there is also a selection of different connectors that differ in terms of current and voltage values.
