Circuit Disconnect and Shorting Terminal Blocks

Sliding Link Shorting Blocks

It is crucial to have a screw lock sliding link terminal block for your test and measurement circuits such as CT or current transformer circuits. ASI sliding link terminal blocks allow for a quick but safe circuit disconnect. Accessories may be ordered for any of our sliding link terminal blocks

ASI offers a broad range of shorting terminal blocks and circuit disconnect terminal blocks that use knife disconnect, switch disconnect, pull up disconnect or a sliding link to open the circuit without disconnecting or disturbing the wiring. The sliding link terminal blocks open up the circuit and also can be equipped with either a two position or four position sliding jumper that provides a short to adjacent terminal blocks, typically used in current transformer, CT circuits. The knife or lever type DIN rail mounted circuit disconnect or opening terminal blocks are available in single level, double level, screw clamp or spring clamp wire termination. Shorting terminal blocks and disconnect terminal blocks are typically used in control panels found in control, measurement and regulation circuits in applications from chemical plants to electric utility power stations.
  

Knife Disconnect Terminal Block Features:

  • Color coded lever which provides a visual indication
    of whether the circuit is open or closed, based on
    the position of the knife disconnect lever.
  • Available in single and double level versions and
    with standard or socket type screw heads.
  • The double level block features a feed-through wire connection on the bottom and a circuit disconnect
    on the upper level, making it an ideal terminal
    block for control loop applications. When wired
    in a control loop you save space with just one
    block and you have the ability to open one side
    of the loop for testing purposes.
  • If you are already using similar knife disconnect
    terminal blocks from Phoenix Contact® then you
    will be pleased to see our alternatives under competitive circuit disconnect terminal blocks.

  • Sliding link disconnect terminal blocks are of the design and style typically found in power and utility applications, such as in a panel where CT or current transformer circuits are wired.
  • Easily secure the circuit opening sliding link and the sliding shorting jumper by tightening the associated screw thereby providing reliability and security in critical current transformer circuits. Particularly popular in electric utility control panels.
  • The 2-position and 4-position sliding jumper, ordered separately, is available for use in a single phase or 3 phase current transformer circuits.
  • ASI can provide a complete ready to install assembly for use in wiring a CT circuit that will include disconnect terminal blcoks, shorting jumpers, end clamps and fuses or standard terminal blocks as required.
