Distribution blocks for load and control current distribution

The SI fuse blocks have screw-in fuses rather than disconnect elements. These screw-in fuses enable simple protection for the individual distribution connections. If tripped, the fuses can be quickly and easily replaced. Along with the standard versions, blocks with signal lights are also available for signaling defective fuses.

The TG disconnect base blocks are equipped with a standardized disconnect zone. The disconnect zone enables the integration of isolating plugs, fuse plugs, or component connectors. This allows the blocks to be used in a highly individual way. Use the blocks to separate or protect signals or to implement diodes or LEDs. The various function plugs are listed in the accessories for the respective item.

The MT knife-disconnect version is a disconnect block with integrated knife disconnection. Instead of the universal disconnect zones, this block has permanently integrated disconnect knives that can be swiveled. The disconnect knives of the MT version are particularly space-saving and remain captive. The disconnect knives, which can be swiveled, can only be opened with a screwdriver. This ensures a high level of safety, as a deliberate action is required to open the disconnect knives.

Like the MT versions, the MTL blocks are a basic disconnect block with permanently integrated disconnect knives. What distinguishes the two versions is that the disconnect knives of the MTL version have a lever. This lever allows the user to operate the disconnect knives without using any tools. However, the MTL version requires more space above the block for this.

The vertical DIN rail adapter can be mounted on NS 35 and NS 15 DIN rails. To mount, simply attach the distribution blocks to the adapter. The adapter is then snapped onto the DIN rail. To prevent the blocks from slipping down, when mounting make sure that the side with the base latch is facing downward. The corresponding mounting adapter is listed in the accessories for the individual blocks. However, you can also directly select blocks including adapters in the product list.

In addition to DIN rail mounting, the blocks can also be mounted directly by means of snap-on flanges. To do this, you need to connect the flanges to the ends of the distribution blocks by means of tongue and groove connection. For longer rows of distribution blocks, flanges should also be integrated between the distribution blocks. Once the flanges are engaged, the blocks can simply be screwed onto the mounting panel. The corresponding flange is listed in the accessories for the respective block.

The distribution block versions for adhesive mounting feature an adhesive pad on the bottom of the block. To mount these blocks, simply remove the protective foil covering the adhesive pad. You can now attach the block to various surfaces. When using this method, make sure that the blocks are always adhered to clean surfaces. It is not necessary to use a primer or roughen the surface beforehand. You will find detailed assembly notes and information regarding the adhesive in the online shop in the download area for the respective products.

The double DIN rail adapter can be snapped onto the NS 35 DIN rail and thus enables the space-saving configuration of several distribution blocks. To mount, attach the distribution blocks to the corresponding adapter feet. The blocks can then be easily snapped onto the DIN rail. We recommend using two snap-on feet for each stand-alone block. The corresponding mounting adapter is listed in the accessories for the 1.5 mm² versions.

So that tests can be performed as quickly and easily as possible, the FIX blocks feature special test pick-offs for test plugs with a diameter of 2.3 mm. The test pick-offs make it very easy to test the blocks with the conductors inserted. In addition, the test pick-offs provide a high level of touch safety during the testing process. The distribution and collection blocks are equipped with one test pick-off per block. The function distribution blocks, on the other hand, have one test pick-off per connection. The reason for this is that the various distribution connections can be separated and tested separately with the aid of the disconnect knives. The individual connections of the fuse block can also be measured separately.

For easy marking of the FIX distribution blocks, the blocks can be marked with self-adhesive marking material (TML or SK). To enable straight and neat marking, the blocks have a flat marking groove specially designed for adhesive markings.
