CDB4/5BK is a modular distribution terminal block in black color with 12 output connections of 4 sq.mm, specially designed for industrial electrical systems where one incoming power source needs to be distributed to multiple outgoing circuits in a safe, compact, and organized manner. In electrical control panels, PLC cabinets, switchboards, industrial automation systems, machine control panels, and OEM electrical assemblies, engineers often require a reliable power distribution point that can take one input and distribute it to several branch circuits without using multiple jumper wires or loose connections.
The CDB4/5BK solves this challenge by providing 1 central input connection and 12 outgoing screw clamp output connections, all internally connected through a common conductive path. This allows clean and secure circuit branching in one compact insulated terminal block. Instead of using multiple separate terminals and jumper links, this modular distribution block simplifies panel wiring, saves DIN rail space, improves conductor organization, and reduces installation time.
The black housing provides a visual circuit grouping advantage in electrical panels. It is commonly used in industrial applications where dedicated circuit grouping, phase identification, load distribution sections, or specific control wiring zones need quick visual recognition during maintenance and troubleshooting. This improves panel readability and makes industrial electrical systems easier to manage.
The CDB4/5BK works as a modular power distribution terminal block, where one incoming conductor is connected at the input side and electrical power is internally distributed to 12 outgoing screw clamp terminals.
Its working design provides:
This design reduces panel wiring clutter and provides a safe, professional electrical distribution arrangement in industrial control systems.
The black housing color improves visual recognition of dedicated electrical sections inside industrial panels.
Safety advantages include:
This improves panel safety and maintenance efficiency in industrial electrical systems.
