CDB4/11(1) Modular Distribution Terminal Block is a compact and high-performance electrical power distribution component specially designed for safe power input distribution, multi-circuit branching, and organized electrical panel wiring in industrial and commercial electrical systems. It is widely used in control panels, switchgear assemblies, PLC systems, automation cabinets, electrical distribution boards, machine wiring systems, and industrial electrical installations where one incoming power source needs to be safely distributed to multiple outgoing circuits in a compact and organized manner. The CDB4/11(1) features 1 input connection with 24 output connections of 4 sq.mm, making it ideal for high-density circuit distribution applications.
In modern industrial electrical systems, multiple outgoing circuits often require a centralized power distribution point. Using manual loop wiring or direct conductor interconnections can create wiring congestion, increase installation complexity, and reduce panel organization. The CDB4/11(1) is designed to solve these issues by providing a modular distribution block with bolt type input connection that allows safe power input and structured outgoing circuit distribution in one reliable electrical component. Its 24 output connections help simplify circuit branching in compact panel installations.
The CDB4/11(1) provides a secure conductor connection with a high-conductivity internal bus path, helping maintain stable electrical continuity while reducing wiring clutter inside panels. A protective shield safely covers the incoming connection, improving electrical safety and protecting the distribution point from accidental contact. Its compact modular construction improves panel space utilization and supports professional electrical wiring layouts.
Manufactured using industrial-grade polyamide housing, the CDB4/11(1) offers excellent electrical insulation, heat resistance, mechanical strength, and long industrial service life. Its rugged design supports reliable performance under vibration, heat, dust, and continuous industrial electrical operation, making it a dependable power distribution solution for professional electrical systems.
