The CDB4/2R is a 4 sq.mm modular distribution terminal block in red colour, designed for phase distribution, positive DC supply commoning, and organized electrical power distribution in industrial control panels, automation systems, switchgear assemblies, machine wiring, and electrical distribution boards. This compact distribution block provides a safe and efficient method to distribute one incoming electrical supply into multiple outgoing circuits, helping reduce panel wiring complexity and improve circuit organization.
In industrial electrical systems, one power source often needs to feed several branch circuits. Using loop wires for this purpose can make panel wiring complicated and difficult to maintain. The CDB4/2R solves this issue by offering a central incoming connection with internally connected multiple output terminals, allowing safe and organized electrical distribution through a single modular unit. This improves wiring efficiency, saves installation time, and creates a professional panel layout.
The red colour (R variant) is commonly used for phase circuit identification, positive DC circuits, emergency supply wiring, and colour-coded electrical distribution systems. Colour-coded distribution blocks help electricians quickly identify circuit functions during installation, servicing, and troubleshooting, reducing maintenance errors in industrial electrical panels.
One of the major advantages of the CDB4/2R is its multi-output distribution design. The block features 1 incoming connection and 6 outgoing 4 sq.mm terminals, making it suitable for applications where one supply point needs to be distributed across multiple circuits. This makes it useful in PLC panels, industrial control cabinets, automation systems, and machine wiring applications.
The incoming side is designed with a bolt-type central feed connection, while the outgoing terminals use secure screw clamp connections for strong conductor retention and stable electrical continuity. This design ensures reliable power transfer while minimizing loose connection risks and voltage drop in industrial applications.
Its compact DIN rail mounting design helps save panel space and simplifies electrical distribution in modern industrial control systems. Instead of using several loop wires and distribution links, the CDB4/2R centralizes power distribution in one modular block, improving panel aesthetics and maintenance convenience.
Manufactured with high-grade polyamide insulated housing, the terminal block offers excellent dielectric insulation, heat resistance, and long-term mechanical durability. The protective insulated body also shrouds the incoming connection point, improving operator safety and reducing accidental contact risk during servicing.
The CDB4/2R is rated for 800V operating voltage, with 64A input current capacity and 32A output current rating, making it suitable for industrial low-voltage distribution systems, machine control panels, PLC cabinets, and automation wiring applications. It supports conductor sizes up to 16 sq.mm on the input side and 4 sq.mm on the output side.
The CDB4/2R is widely used in:
With its red circuit identification colour, modular multi-output design, secure conductor connections, and industrial-grade electrical performance, the CDB4/2R is a reliable solution for professional electrical power distribution applications.
