Disconnect 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 Disconnect Terminal Blocks are typically multi-conductor, feed-through or multi-level terminal blocks with an integrated disconnect zone. The disconnect zones are standardized and accommodate a range of function plugs, which result in different types of function terminals. Adding a fuse plug results in the disconnect terminal becoming a fuse terminal block, adding a component connector results in a component terminal block and adding a feed-through connector results in a feed-though terminal block. Isolating plugs that can be integrated, such as lever-type disconnect knives of the knife-disconnect terminal blocks, enable quick changeover between the two switching states. This easy changeover can enable the fast measurement of individual circuits. Basic disconnect terminal blocks, with the addition of a removable plug, results in the most versatile terminal block in a control cabinet.
