CX2.5BU is a high-performance 2.5 sq.mm spring clamp feed-through terminal block designed to provide safe, stable, and maintenance-free electrical connections across a wide range of industrial and commercial electrical applications. Built for modern control panel requirements, this terminal block delivers efficient conductor termination with enhanced vibration resistance and long-term reliability.
Engineered with spring clamp connection technology, CX2.5BU ensures consistent contact pressure throughout its service life. Unlike traditional screw terminals that may loosen over time due to thermal cycling or vibration, the spring clamp mechanism automatically maintains secure conductor retention. This significantly reduces maintenance requirements and improves operational safety in demanding environments.
The terminal block is designed for DIN rail mounting, making installation fast, organized, and space efficient in electrical cabinets and panel assemblies. Its compact footprint enables higher wiring density while maintaining accessibility for wiring, inspection, and servicing. This design is especially valuable where panel space optimization is essential.
Featuring a blue insulated housing, CX2.5BU is commonly used for neutral conductor identification, circuit separation, and structured wiring layouts. Color-based terminal identification improves panel organization and supports easier troubleshooting and maintenance procedures.
The terminal supports both solid and stranded conductors, providing flexibility across different industrial wiring standards and applications. Conductors are inserted through the top-entry design and secured using a spring-operated mechanism activated with a standard screwdriver. Once released, the internal spring applies constant force to ensure reliable electrical continuity.
Manufactured using high-quality polyamide insulation material, the housing provides excellent electrical insulation properties together with mechanical durability and flame resistance. The material maintains dimensional stability under varying temperature conditions and performs reliably in industrial environments exposed to vibration, heat, and continuous operation.
With a rated voltage of up to 1000V and rated current of 24A, CX2.5BU supports dependable power and signal transmission in industrial electrical systems. Its compact 5 mm width allows installers to maximize panel capacity while maintaining clean and professional wiring arrangements.
The terminal block also offers strong resistance to electrical pollution conditions and transient surge conditions, contributing to improved safety and long-term performance in industrial electrical installations.
CX2.5BU is widely selected for applications where secure conductor retention, efficient installation, reduced maintenance, and long-term operational stability are required.
