High Current Terminal Blocks

Terminal blocks are a modular block with an insulated frame connecting two or more wires in a reliable manner. A clamping component and a conducting strip are used to secure and organize connecting wires, allowing multiple outgoing wires to join to one singular incoming wire. Wires are secured to the terminal blocks with screw connections, spring cage connections, push in connections (requiring the use of ferrules on the wires), fast connections, or barrier connections (requiring ring or spade terminals on the wires). Terminal blocks are the perfect solution for complicated control circuits that require secure, well-organized and semi-permanent wire connections that can easily be switched out for repair or inspection in the field. Within a control board, terminal blocks are snapped firmly into place on a mounting or DIN rail. When modifications to the circuit are performed, they can easily be added or removed from the rail without interfering with other wire connections.

Phoenix Contact High-Current Terminal Blocks are designed for a nominal voltage of up to 1,500 V and can be snapped onto a DIN rail or screwed onto a mounting plate. Corresponding pick-off terminals allow easy feed-in and potential distribution. The PTPOWER terminal blocks with patented Power-Turn spring connection technology allow large conductors to be connected quickly and easily using a standard screwdriver and  a single lever movement. Up to three steel pressure springs work in combination with the prismatic terminal body base to create a vibration-resistant conductor connection. The compact, high-current feed-through terminal blocks with screw connection are suited for use in renewable energy generation. Four integrated pick-off terminals provide easy feed-in or potential distribution. The appropriate potential distribution blocks are implemented with screw bridges.
