Feed-through terminal blocks
Feed-through terminal blocks are characterized by two terminal points and a compact design. The large cross-section range of the feed-through terminal blocks allows universal use in every application. Along with the standard feed-through terminal blocks for wiring with copper litz wires, for example, Phoenix Contact also provides Al/Cu terminal blocks. The universal terminal blocks enable the connection of aluminum and copper conductors in just one terminal block.
Multi-conductor terminal blocks
Even more compact wiring is possible with the multi-conductor terminal blocks from Phoenix Contact. Multi-conductor terminal blocks are feed-through terminal blocks with three or four connections that are all routed via the same current bar. This allows you to connect up to four conductors with individual wiring per terminal block. The design of the terminal blocks means that fewer terminal blocks and supply lines are required for wiring. Along with an improved overview, this also enables wiring or potential distribution in tight spaces.
Double-level terminal blocks
Compared to the feed-through terminal blocks, the double-level terminal blocks enable even higher wiring density and greater flexibility than the multi-conductor terminal blocks. To put it simply, double-level terminal blocks are two feed-through terminal blocks in one terminal block. To make this possible, the terminal blocks have two levels, each of which carries a potential. If necessary, these levels can be quickly and easily connected with vertical PV bridges, which means that the double-level terminal blocks can also be used as multi-conductor terminal blocks. To reduce manual bridging effort, the portfolio also includes terminal blocks with permanently integrated bridging. These versions have “PV” in the product name. The double-level terminal blocks with lateral conductor connection feature offset levels. The offset enables unhindered access to the lower connection level and its push button or screw, even when fully wired.
Multi-level terminal blocks
Multi-level terminal blocks are terminal blocks that have multiple levels. Unlike double-level terminal blocks, they usually have three or four levels, but are similar in design to double-level terminal blocks. Each of the levels carries its own potential. Depending on the terminal block version, either just the top two levels or all levels can be connected easily with vertical bridging. In addition to the normal versions, those with integrated PV bridging are also available. With those, manual bridging is not necessary because all levels are connected at the factory. In addition to the simple feed-through versions, the range of four-level terminal blocks and three-level terminal blocks also include versions with one or more functional levels. The function level usually has a disconnect zone in which either a knife disconnection or a universal disconnect zone for various function connectors is installed. The portfolio also includes special motor terminals for the space-saving connection of three-phase motors. The bridging option for simple phase bridging on each level reduces the wiring time.
