China Best Barrier Terminal Block Connector 9.5mm

Complete China Best Barrier Terminal Block Connector 9.5mm combine a ring cable lug connection with the advantages of the complete terminal block system. The uniform system accessories, such as the standardized plug-in bridges, provide considerable time savings during wiring. Using continuous marker strips, the terminal blocks can be marked across a large surface, and each terminal point can be marked clearly. The transparent design of the strips means you retain a clear overview when bridging.

If you need terminal blocks and strips for a new installation or part replacement, order them from SUN and enjoy premium quality at affordable prices. We have a large selection to choose from, including barrier strip connectors, feed-through spring cage terminal blocks, models designed for use with high current applications, and many others. SUN makes terminal blocks and strips you can trust for reliable connections and consistent performance. 

How to decide the China Best Barrier Terminal Block Connector for you?

Choosing the right type of connector for your application may seem trivial but, in fact, is more complex than you may realize. The aspects of terminal blocks that need to be considered are typically current requirements, voltage requirements, the wire being used, mechanical strength, and the environment.

1. Current requirement

Current requirements are arguably the most important aspect to consider because pushing too much current through a terminal block can result in overheating and, therefore, the destruction of the terminal block. When looking for a terminal block, be sure that the chosen block can, in fact, handle the current that you expect to use plus 50 percent more. For example, if an expected current of 2 A is to be drawn from a block, then a terminal block with a current rating of 3 A would be sufficient.

2. Voltage requirements

Just like the current draw, the voltage also needs to be taken into account. The voltage causes problems with dielectric breakdown such that a voltage too high for a terminal block could cause current leakage between adjacent terminal blocks. However, high voltage requirements are often rare in design, which is why voltage considerations are typically ignored for voltages under 100 V. However, it is still important that this figure is checked before a terminal block is chosen!

3. Wire being used

Not all wires are equal, and each wire type has its own advantages and disadvantages. For example, when choosing a terminal block for a cable, be sure to know the size of the cable (can it physically fit into the terminal block?) as well as if it’s single-core or multi-core. Multi-core wire does very well in screw terminals, whereas single-core wire does well in push-fit connectors.

4. Environmental/mechanical strength

The environment is a very important aspect to consider when choosing a terminal block. Some terminal blocks may be mechanically strong and able to handle high currents, but if the connection is being used in a naval environment, then the salty air could be detrimental to the metal contacts. The environment could also have wide temperate swings or contain mechanical vibrations, which make screw terminations unreliable.
