CX2.5/3R is a 2.5 sq.mm spring clamp feed through terminal block designed for secure conductor termination, reliable electrical connectivity, and organized panel wiring in industrial electrical systems. This compact feed through terminal block is specially engineered for modern control panels, automation systems, switchboards, PLC panels, machine wiring systems, and industrial electrical assemblies where fast wiring, vibration-resistant connections, and maintenance-friendly termination are essential.
Unlike conventional screw clamp terminal blocks, CX2.5/3R uses spring clamp connection technology, which ensures secure conductor holding through spring pressure. The conductor is inserted using a screwdriver-operated mechanism, and once the tool is removed, the spring clamp automatically applies pressure on the conductor, creating a firm and reliable electrical connection. This design minimizes the risk of loose wiring due to vibration, thermal cycling, or mechanical stress.
One of the major advantages of CX2.5/3R is its maintenance-free spring clamp design, which eliminates the need for periodic retightening required in screw-type connections. This improves electrical reliability and reduces maintenance effort in industrial installations.
The terminal block is designed for 2.5 sq.mm conductor capacity, making it suitable for signal circuits, control wiring, automation panels, and industrial power distribution systems requiring compact and efficient termination.
Its red color housing provides quick visual identification in electrical panels where color-based wiring segregation or circuit differentiation is required. Color-coded terminal blocks improve panel organization, maintenance speed, and troubleshooting efficiency.
