Particularly in testing and measurement technology, various terminal blocks are used which enable the easy manual disconnection of circuits. The knife-disconnect terminal blocks from Phoenix Contact have an easy-to-operate lever disconnect knife. The basic disconnect terminal blocks have a standardized disconnect zone for accommodating component connectors, fuse plugs, isolating plugs or feed-through connectors.

Knife-disconnect terminal block
Knife-disconnect terminal blocks feature captive lever-type disconnect knives that can be swiveled. These knives are operated with a standard screwdriver, allowing circuits to be quickly disconnected and closed for test purposes, for example. Test points are integrated into the terminal points such that the tests can be carried out with connected conductors. The disconnect knives latch into clearly recognizable end positions so that they are not actuated accidentally. Optional switching locks are available to completely prevent lever-type disconnect knives from being actuated.
Disconnect terminal blocks and isolating plugs
Disconnect terminal blocks are usually feed-through, multi-conductor, or multi-level terminal blocks with an integrated disconnect zone. The disconnect zones are standardized and accommodate a range of function plugs. The inclusion of a function plug results in different types of function terminals. By including a fuse plug, the basic disconnect terminal block becomes a fuse terminal block. With a component connector, the terminal block becomes a component terminal block. With feed-through connectors and feed-through locks, a basic terminal block can be converted into a feed-through terminal block or a terminal block without feed-through. The isolating plugs that can be integrated, such as the lever-type disconnect knives of the knife-disconnect terminal blocks, enable quick changeover between the two switching states. This easy changeover enables, for example, the fast measurement of individual circuits. This means that the basic disconnect terminal block, with the aid of a removable plug, is the most versatile terminal block in a control cabinet.
