PUSH-IN Terminal Block
August 2021

It’s hard to visualise a wiring technician without a screwdriver or some special wire fastening tool. Today, the foundations of industrial automation technology have evolved to the point that the ubiquitous screwdriver has become somewhat redundant. Global automation is fast discovering the advantages of PUSH-IN Terminal Block technology. Widely regarded as tool-free connection Terminal Blocks, this new wire-loading technology does not need a screw driver or tools for wiring.


What’s the connection with screwdrivers?

Conventional wiring panels commonly use screw clamp Terminal Blocks in which screw and clamp arrangement holds the wire against the current bar. However, as the density of wiring and the connections have grown exponentially, many industrial automation applications have discovered the need for change from the tedious and time- intensive screw clamp wiring methodology. Furthermore, there always exists a possibility of loose connection due to human dependent tightening torque of screw clamp. The sheer number of wire connections in the automation panel or a marshalling cabinet is much higher than any other application. Therefore, conventional screw clamp technology is no longer preferred by the Automation Industry or for DCS wiring.

PUSH-IN Terminal Blocks do not require screwdrivers.

The biggest advantage of the PUSH-IN Terminal Block technology is that a wiring technician does not need a screwdriver or a clamp actuator tool for wiring. The lugged wire is simply pressed against the spring clamp for a firm connection to be made with the current bar. This removes any possibility of loose connection and makes human effort independent gas tight connections.



With this level of wiring ease, it’s no wonder that PUSH-IN Terminal Blocks have become the first choice of the Automation and DCS industry. Efficiency analysis studies have shown that using push-in technology makes 400% faster connection saving 75% of wiring time as against conventional screw clamp connection technology.

Managing wire density is easier.

As industrial automation goes up, so also does wiring density. This has led to a situation where wire management has become a serious concern. With PUSH-IN Terminal Blocks, dense wiring situations are much easier to manage as the wiring technician simply has to push in the wire to make a firm connection. From a skilled manpower point of view, what's more important is that irrespective of the varying wiring capabilities of technicians, there is no additional applied-force required for wiring as the springs inside the Terminal Blocks automatically engage and complete the connection.


When you choose the next generation PUSH-IN Connection Technology, you can save a significantly higher value in project completion time. In addition, the ability to manage super dense and complex wiring projects becomes easier with the compact space- saving design. Put together, this leads to a much more attractive Total Cost of Ownership that makes next-generation Connectwell PUSH-IN Terminal Blocks the preferred connection standard for automation projects.
