CDB4/5(1) is a modular distribution terminal block with 12 output connections specially designed for industrial electrical systems where single input power distribution to multiple outgoing circuits, compact DIN rail installation, and organized electrical branching are required. In electrical control panels, PLC cabinets, switchboards, industrial automation systems, machine control panels, and OEM electrical assemblies, engineers often need to distribute one incoming power supply to multiple output circuits safely and efficiently.
Using jumper wires or multiple standard terminals for such applications increases wiring complexity, creates clutter, and consumes more panel space. The CDB4/5(1) solves this challenge by providing 1 central input connection and 12 distributed output connections in one compact insulated terminal body, making circuit branching simpler, safer, and more organized. This improves wiring reliability and maintenance accessibility inside industrial electrical panels.
Unlike standard distribution blocks, the (1) series design is specially configured where the input connection point is located at one end instead of the center, making it useful for panel layouts where cable routing needs side-oriented power entry. This provides installation flexibility and improves conductor management in compact electrical systems.
The CDB4/5(1) works as a modular power distribution terminal block, where a larger incoming conductor is connected through a stud & bolt input connection, and power is internally distributed to 12 outgoing screw clamp terminals.
Its working design provides:
This design reduces manual jumper wiring and creates a clean, professional power distribution arrangement inside industrial electrical panels.
The CDB4/5(1) improves electrical safety by creating a controlled and organized power distribution point inside industrial panels.
