M4 Screw Terminal
Products Description
Our M4 Screw Terminals are pre-assembled fastener terminal blocks designed for secure and stable wire connections. They integrate an M4 screw and a precision-machined terminal frame for optimal conductivity and torque strength. They are ideal for wall switches, miniature circuit breakers (MCBs), photovoltaic fuses, and other applications requiring screw-clamp connection terminals.
Product Features
1. Unique Design
(1). Pre-assembled design: The Screw Type Terminal and the wiring frame are carefully pre-assembled, with a compact structure, convenient and quick installation, saving installation time and space, and improving work efficiency. This design also effectively avoids the problems of looseness and poor contact, ensuring the stability of electrical connections.
(2). Double cage terminal design (if available): If the Rail Terminal Block has a double cage terminal structure, it can provide better fixing and support, enhance the reliability of the connection, and is suitable for application scenarios with high requirements for connection stability.
2. High-quality materials
(1). Electrical Terminal Screws: The screws are M4 specifications and are zinc-plated. The zinc coating has good rust and corrosion resistance, which can effectively extend the service life of the M4 Zinc Plating Screw Wire Terminal and ensure stable connection performance in various harsh environments.
(2). Wiring frame material: The wiring frame is made of high-quality metal materials with good conductivity and mechanical strength. It can withstand certain external forces and vibrations to ensure the reliability of electrical connections.
3. Strong adaptability
Applicable to various types of electrical equipment, such as wall switches, wiring switches, molded case circuit breakers, photovoltaic fuses, etc., which can meet the needs of external wires in different scenarios. Its universal design allows it to perform well in different electrical systems.
Product Advantages
Improve connection reliability
The design of the Screw Type Terminal frame makes the connection between the wire and the contact more secure, reduces poor contact caused by vibration, looseness, etc., and thus improves the reliability of the entire electrical system. This is especially important for equipment that requires long-term stable operation and can effectively avoid failures and safety hazards caused by contact problems.
01
Improve connection reliability
The pre-assembled design reduces the workload and time cost of on-site installation and improves installation efficiency. At the same time, due to the durability and stability of the Electrical Terminal Screws, the maintenance cost and replacement frequency of the equipment are reduced, saving a lot of operating costs for the enterprise.
02
Compliance with standards
The Rail Terminal Block complies with relevant electrical safety standards and specifications, such as IS09001-2015, IATF16949, ROHS, REACH, etc., to ensure the safety and reliability of the product. You can use our products with confidence to provide reliable protection for your electrical equipment.

Manufacturing process
| Screw processing | Use advanced cold heading technology to process the screws to ensure the dimensional accuracy and surface quality of the Circuit Breaker Terminal. |
| Wireframe stamping | Use high-precision stamping equipment to stamp the metal sheet to form the shape of the Screw Type Terminal, and perform surface treatment to improve its corrosion resistance and conductivity. |
| Moving contact manufacturing | The moving contact is manufactured through multiple processes, including material smelting, molding, surface treatment, etc., to ensure that the performance of the moving contact meets the requirements. |
| Assembly | The processed screws, wireframe, and moving contact are pre-assembled and undergo strict quality inspection to ensure the quality of the M4 Screw Terminal. |
