With the 8.25 mm Terminal Block Strip from SUN, you can connect conductors safely and conveniently. In combination with Push-in connection technology, the screw connection principle with spring-guided screw makes wiring quick and easy. The SUN 8.25 mm Terminal Block Strip is available for DIN rail or direct mounting. As China barrier terminal block manufacturers, SUN offers an electrical terminal block to meet the needs of most any application. A SUN China barrier terminal block can be found to support either wire-to-board or wire-to-wire configurations. 

How does 8.25 mm Terminal Block Strip Work?

Each strip will have a pair of screws arranged such that each screw connects to a separate conductor on either end of the strip. Alternatively, terminal strips have several screws along two strips, creating a bus bar for the distribution of power.

How to decide the Terminal Block Strip 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.
