Spring terminal block

• The main reason of high temperature when using terminal block

  Aug 20, 2024

  There are two main reasons why terminal blocks may generate high temperatures:1. Loose terminals leading to increased circuit resistance, resulting in overheating.2. Control circuit experiencing overcurrent due to reasons such as high power supply voltage or load short circuit faults.Here are some solutions to these issues:1. Check the working voltage from the secondary coil of the transformer to the distribution cabinet and then to the electrical equipment.2. Ensure proper grounding from the transformer to the distribution cabinet to prevent common faults in grounding.

  When using PCB terminal blocks for wiring applications, it is important to keep in mind the following precautions:1. Always ensure that the power is switched off before starting any wiring operations. Never attempt to work on the terminal blocks while they are live. If you are unsure whether the power is off, use a voltage tester to verify. Additionally, if there are sliding buttons on the terminal blocks or switches, it is advisable to replace them if they are worn out to prevent any risk of electric shock.2. When connecting to the power source, make sure to install PVC conduit for wire routing. Avoid leaving wires hanging loosely without any proper support or fixation on support brackets or busbars.3. Pay attention to the length of the wires when connecting to the switch box. It is recommended to keep the wire lengths within a suitable range and properly route them through conduits. Avoid pushing the wires directly into the switches for fixing.By following these precautions, you can ensure safe and efficient operation of the PCB terminal blocks.
