Many users do not know what they should pay attention to when buying terminal blocks because of their purchase? Based on this point, Zhiheng Zhuonang compiled some notes on buying terminal blocks for your reference!

Precautions for purchasing terminal blocks

1、 Current

Current can be said to be an important aspect to consider when purchasing terminal blocks, because excessive current will cause terminal blocks to heat up, and overheating temperature may damage terminal blocks. Therefore, when selecting the terminal blocks, it is necessary to ensure that the selected terminal blocks have higher current processing requirements. If the application requires the expected rated current of 2A, it is sufficient to select the terminal blocks with rated current of 3A.

2、 Voltage

Voltage is also a problem that needs to be taken into account for terminal blocks, because voltage will cause dielectric breakdown, so that too high voltage of terminal blocks may lead to current leakage between adjacent terminal blocks. Although high voltage requirements are rarely seen in design, which is why voltage considerations are usually ignored when the voltage is lower than 100V, it is very important to check voltage parameters before selecting terminal blocks.

3、 Environmental performance

Environmental factors are also important issues to consider when buying terminal blocks. Because environmental factors such as corrosion, high temperature and vibration will affect the performance of terminal blocks, it is necessary to ensure that terminal blocks have high mechanical strength and good environmental performance.
