Core strengths
Efficient conductivity and high current carrying capacity: Adopting a thickened conductor design, it supports high current transmission (such as 145A), adapts to large cross-sectional wires of 50mm ² and above, and meets the high load requirements of industrial scenarios.
Modular installation and space optimization: The rail type structure is compatible with standard electrical rails, supports multi specification component combinations, and can achieve "one in, multiple out" distribution, improving wiring efficiency and saving control cabinet space.
Durability and stability: The metal casing (such as aluminum terminals) is paired with high-strength insulation materials, which are resistant to deformation and aging, suitable for long-term high-frequency use, and ensure stable circuit connections.
Main material
Conductive parts: Based on copper or aluminum (such as aluminum terminals), some key contacts may be treated with tin/silver plating to enhance conductivity and oxidation resistance.
Insulation shell: Made of engineering plastics such as PA66 and PBT, with flame retardant (UL94 V0 grade) and temperature resistance (-40 ℃~125 ℃) characteristics. Some models may add fiberglass reinforcement for mechanical strength.
Fixed components: metal buckle or screw structure, ensuring a stable connection with the guide rail and wire, reducing the risk of loosening.
Product Features
Standardized design: Compliant with guide rail installation specifications, compatible with modular components such as circuit breakers and relays, supports free cutting (such as cutting length as needed), and adapts to different cabinet sizes.
Multi scenario adaptation: Supports "one in, multiple out" distribution function, suitable for scenarios such as distribution box renovation, home weak current layout, industrial control cabinets, etc., especially suitable for high current and multi circuit wiring needs.
Convenient installation: No need to drill holes, fixed with horizontal buckles, and equipped with aluminum rails and other accessories for quick positioning, reducing construction difficulty and improving installation efficiency.
This series of junction boxes achieves safe, efficient, and multi scenario circuit connection requirements through the collaborative design of materials and structures, and is an indispensable basic accessory in electrical systems.
