Barrier Terminal Blocks

• 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.

  Aug 11, 2024

  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. If you have any further questions or need assistance, please feel free to contact us.

• Terminal Blocks: The Essential Guide for Safe and Reliable Electrical Connections

  Sep 24, 2025

  What Are Terminal Blocks? Terminal blocks (also known as connection terminals or terminal connectors) are modular, insulated devices that allow multiple wires to be safely connected together. They are widely used in electrical control systems, industrial automation, building wiring, and various electronic devices. By providing a secure and organized way to connect circuits, terminal blocks ensure stable performance and easy maintenance.   Main Types of Terminal Blocks When searching for terminal blocks, users often want to know what types are available and which one suits their project. The most common categories include:   Screw Terminal Blocks: Traditional and reliable, tightened with screws to secure the wire. Spring Clamp Terminal Blocks: Tool-free, quick connection with strong vibration resistance. Barrier Terminal Blocks: Provide clear separation between circuits, ideal for power distribution. Pluggable Terminal Blocks: Easy to connect and disconnect, suitable for modular designs. DIN Rail Mounted Terminal Blocks: Installed on standard DIN rails for organized control cabinets.   Key Applications Terminal blocks are widely used across industries:   Industrial Automation – Control cabinets, PLC systems, and motor control centers. Power Distribution – Electrical panels, circuit breakers, and transformers. Building Wiring – Lighting systems, HVAC, and security systems. Electronics & Appliances – Home appliances, testing instruments, and PCB connections. How to Choose the Right Terminal Block? Users searching online often want to compare options. Here are some key factors to consider: Rated Current and Voltage – Ensure the terminal block meets your electrical requirements. Wire Size Compatibility – Match the wire gauge (AWG/mm²) for safe connections. Connection Method – Screw type for secure, spring clamp for convenience.
