Ready-to-connect manifold and distribution blocks with 4, 6, 12 and 18 terminal points, as well as individual plates with two terminal points, are available in eleven colors for intuitive and safe installation. PTFIX blocks are available in nominal sections of 1.5 mm², 2.5 mm², 4 mm² and 10 mm². The reduced insertion forces of the Push-in connection technology thus allow rigid and flexible conductors with ferrules from 0.25 mm² to be inserted easily and directly.

PTFIX-function
The PTFIX-function distribution block family is made up of various interrupt and fuse blocks. The distribution blocks are available with seven terminal points and a nominal section of 2.5 mm². Like the PTFIX blocks, the blocks have a front push-in connection. However, they differ in their design and function. The collective connection of the function distributor blocks is connected to the distribution connections via the individual break zones or fuse links. Thus, the function inserts represent the connecting elements between the various distribution connections and the collective connection. This design allows you quick and easy interruption or fused protection of individual signal lines.
PTVFIX
Unlike the PTFIX blocks, the PTVFIX blocks have a side push-in connection. The lateral conductor arrangement enables particularly clear and flat wiring without bending radii. Apart from this, however, the PTVFIX blocks do not have any technical differences from the already tested PTFIX distribution blocks. The PTVFIX blocks are available in the 2.5 mm² section with 6, 12 and 18 terminal points. PTVFIX blocks are available in five standard colours. With the integration in the online configurator you can order other color variants. This guarantees a clear and color-coded assignment of the conductors.
PTVFIX multiblock
The PTVFIX multiblocks are the first FIX distribution blocks with more than one potential. Unlike the other distribution blocks, the multiblocks do not have a built-in jumper. In this way, the blocks incorporate a potential for every two terminal points. This property makes them especially suitable in areas such as installation in buildings. Quickly and easily connect the phase, neutral and ground conductors in a single, compact block that takes up little space.

TG
The TG variant is a basic interrupt block with a standard interrupt zone. The break zone allows the implementation of different function sockets.
Use, for example, the interrupt pins to make it easier to separate the signals. With TG blocks, fuse protection by means of suitable fuse heads or the implementation of constructive elements is not a problem either. The various function connectors are stored in the article accessories.
MT
The MT variant is an interrupt block with integrated knife interrupt. Instead of universal shutdown zones, this block has permanently integrated rotary sectioning knives. Fixed integration offers advantages and disadvantages. The permanently installed knives limit the functions of the MT block compared to the TG block, since the MT variant is only suitable for the interrupting function. On the other hand, the sectioning knives save a lot of space and do not get lost. Another advantage is that the rotary disconnector blades can only be opened with a screwdriver. Therefore, to open the disconnection point, a conscious action is needed. If you need a block for deliberate signal separation only, this block is recommended.
MTL
The MTL function distributor block also belongs to the interrupt blocks. The MTL blocks differ from the MT variant only in the sectioning blade. Disconnecting knives are also permanently installed, but have a lever. For this reason, sectioning knives are also called lever sectioning knives. Due to the lever, MTL function manifold blocks require a little more space above the block, but can be opened and closed without tools. For this reason, the MTL version is particularly suitable for applications where there is sufficient space above the bushing and where regular knife interruption is required.
SI
The PTFIX 10/6X4-SI… fuse blocks have rotating fuses instead of switching elements. Rotating fuses allow easy fusing of the various distribution connections. In addition to the standard variant, blocks with indicator lights are also available for indicating faulty fuses.

Bridges
The distribution blocks of the FIX families have an integrated jumper. Through this bridge, all the distribution connections are connected to each other and to the collective connection. This reduces the wiring effort in the potential distribution. The blocks can be used directly after unpacking. If you need more than one distribution block with 18 terminal points, the push-in distribution blocks and collector blocks can be easily expanded with the standard 2-pole plug-in jumpers from the CLIPLINE complete system. Snap the blocks together with the tongue-groove connection. Once the blocks are connected, they can be easily extended with a plug-in jumper via the external connections. Wire jumpers (FBSW…) from Phoenix Contact are suitable for more specialized bridging tasks. Cable jumpers can also be installed in the wiring space of distribution blocks. Jumpers are characterized by having a flexible, insulated wire between the contacts. This makes the bridge particularly flexible. You can use wire jumpers when standard jumpers cause difficulties.
Tests
To carry out the tests as quickly and easily as possible, the push-in distribution blocks have special test sockets. Test taps make it easy to check blocks with conductors plugged in. In addition, the sockets offer a high level of safety against contact during the test procedure. The distribution and collector blocks are equipped with one test tap per block. The function distributor blocks, on the other hand, have one test socket per connection. The reason is that the different distribution connections can be separated and tested separately by disconnecting knives. Individual fuse block connections can also be measured separately. To facilitate the checking of the distribution blocks, the standardized test system has test pins of different colors with a diameter of 2.3 mm. The contact of the plug is divided into four slightly bent contact pins. This design creates elastic deformation when the trial pins are inserted. This holds the test plug in the test socket and establishes a secure contact with the bus bar. In addition, the blocks can be directly tested with standard 2.3mm test leads.
Lettering
To make it easier to label the FIX distribution blocks, the blocks can be marked with the self-adhesive marking material (TML or SK). For straight and clean marking, the blocks have a specially designed flat marking groove for adhesive marking.
Mounting
Distribution blocks from the FIX family can be integrated into your solution in various ways using different mounting adapters and block variants. Use the adapters and fix the blocks to the DIN rail or directly to the mounting plate using a cable tie. There are also adhesive versions for quick and easy mounting.

Longitudinal to the DIN rail
Horizontal DIN rail adapters are available for NS 15 and NS 35 DIN rails. For mounting insert the distribution block into the corresponding adapter feet. The block is then easily snapped onto the DIN rail. We recommend the use of two fixing feet for each independent block. The quantity can be reduced in jointed distribution block solutions. You will find the corresponding mounting adapter in the accessories for the respective block.
Cross to DIN rail
A separate adapter is also available for cross-rail mounting to the DIN rail. The adapter for vertical DIN rail can be mounted on DIN rail NS 35 and NS 15. For mounting you just have to slide the distribution blocks into the adapter. Again, the adapter fits over the DIN rail. To prevent the blocks from slipping down, you should ensure that the side with the base anchor faces downwards during assembly. You will find the corresponding mounting adapter in the accessories for the respective block.
Direct mounting
In addition to rail mounting, the blocks can also be directly mounted using snap-on flanges. To do this, the flanges must be placed at the ends of the distribution blocks. In the case of the longer distribution block rows, flanges must also be integrated between the distribution blocks. Once the flanges have been fitted, the blocks can be easily bolted to the mounting plate. You will find the corresponding flange in the accessories of the respective manifold.
Adhesive mounting
Variants of the distribution block for adhesive mounting have an adhesive pad on the bottom of the block. To assemble these blocks, simply peel off the protective film from the sticky pad. Now you can fix the block on different surfaces. When using the blocks, make sure that they are only stuck on clean surfaces. It is not necessary to use a primer or pre-sand the surface. You will find detailed installation instructions and information on the adhesive in the download area of the respective products in the online shop.
Double rail adapter
The PTFIX blocks with a minimum section (1.5 mm²) have another rail adapter for mounting on a horizontal rail. The adapter can be snapped onto the NS 35 and thus allows the mounting of various distribution blocks in a space-saving manner. For mounting, slide the distribution blocks into the corresponding adapter feet. The blocks can then simply be snapped onto the DIN rail. We recommend the use of two fixing feet for each independent block. You will find the corresponding mounting adapter in the accessories for the 1.5 mm² variants.
