The function of a low-voltage circuit breaker
2026-04-13 [ Industry News ]
A low-voltage circuit breaker is a type of switchgear that integrates control and protection functions. It is mainly used in power distribution systems with an AC voltage of 1000V or a DC voltage of 1500V or below. It can both manually or electrically connect and disconnect circuits, and can also automatically cut off the power supply when a fault occurs in the circuit to ensure electrical safety. Core protection functions1. Overload protection: When the line current exceeds the rated value and persists for a certain period of time, the circuit breaker will automatically open to prevent e......
The Difference Between Terminal Blocks and Copper Lugs？
2026-04-11 [ Industry News ]
1. Definitions and Functions**Terminal Blocks****Definition:** A terminal block is an accessory product used to facilitate electrical connections. Typically installed between wires and electrical equipment, it serves the function of transmitting electrical current and signals. **Function:** Its primary purpose is to simplify the connection and disconnection of wires while ensuring the reliability and safety of the electrical connection. Terminal blocks can streamline the installation process, enhance maintenance efficiency, and reduce the failure rate caused by poor contact. **Copper......
Are copper terminal blocks heat-resistant?
2026-04-10 [ Industry News ]
**Key Temperature Resistance Characteristics*** **Pure Copper (Red Copper):** Melting point of approximately 1083°C; features high thermal conductivity (approx. 401 W/(m·K)), enabling rapid heat dissipation to prevent localized overheating.* **Brass:** Composed of copper and zinc; exhibits relatively poor temperature resistance with a lower melting point (approx. 900–940°C) and is prone to softening and deformation at high temperatures.* **Tin-Plated Copper Terminals:** According to the national standard GB/T 14048.1-2023, at an ambient temperature of 40°C, ......
Are quick-connect terminals safe?
2026-04-08 [ Industry News ]
The safety of quick-connect terminals is not absolute; rather, it depends on several critical factors, including product quality, the operating environment, installation procedures, and the load current. Provided they are selected and used correctly, these terminals can deliver safe and reliable connections.**Core Factors Affecting Safety****Product Quality and Certification:** The foundation of safety lies in the product itself. High-quality products typically utilize oxygen-free copper or certified copper alloys, often featuring surface plating to mitigate the risk of oxidation. More importa......
The Ultimate PCB Connection Tool: A Comprehensive Guide to Plug-in Terminals
2026-04-05 [ Industry News ]
I. Fundamentals of Pluggable TerminalsImagine two PCB boards needing to connect as quickly and seamlessly as snapping together LEGO bricks; the pluggable terminal acts as that magical "connector." Typically comprising a male header and a female receptacle, these terminals establish electrical continuity through the precise mating of metal contacts. They serve as the circuit's "quick-release interface," not only resolving the irreversibility inherent in soldered connections but also offering a more compact and reliable alternative to traditional wire connections. Common ......
