PTV disconnect terminal blocks and knife-disconnect terminal blocks

Disconnect and knife-disconnect terminal blocks

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.

More information


  • Convenient separation of circuits with lever-type disconnect knife, isolating plug, or rotary contact
  • Convenient current measurement thanks to testing options on either side of the disconnect point
  • Safe operation, because the disconnect lever is latched into the end positions
  • Clear identification of the disconnect point with color marking
  • Individual assembly with disconnect element, fuse plug, component connector, and feed-through connector

New products

CLIXTRAB multi-conductor terminal blocks with integrated surge protection plug
CLIXTRAB multi-conductor terminal blocks for surge protection
Lightning protection for safety-related systems

CLIXTRAB, the combination of a terminal block and surge protection, was designed for safety-relevant applications. The new multi-conductor terminal blocks enable lightning protection in the tightest of spaces for applications with redundant setups and for signal marshalling.

These are the main features

  • Fast conductor connection thanks to Push-in technology
  • Easy integration of the surge protection thanks to simple plug-in contact
  • Space-saving TWIN design with three connection points for applications with a redundant power supply design or for signal marshalling in the indoor system
  • Space-saving QUATTRO version with four connection points for redundant installation of the outdoor system, for example to expand the system

These are the advantages

  • Push-in connection
  • Nominal cross-section of 2.5 mm²
  • Double function shaft
  • Testing option with test points

Knife-disconnect terminal block

Knife-disconnect terminal blocks feature captive swiveling lever-type disconnect knives. These knives are operated with a standard screwdriver, allowing circuits to be quickly disconnected and closed, e.g., for test purposes. Test points are integrated into the terminal points so 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 the lever-type disconnect knives from being actuated.

Isolating plugs

Disconnect terminal blocks

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, the basic terminal block can be converted into a feed-through terminal block or a terminal block without feed-through. On the other hand, 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.
