1×16mm² Input, 8×4mm² Output Side Entry Distribution Block – CDB4/3(1)

Product Description

The CDB4/3(1) Distribution Terminal Block is a high-performance modular power distribution block designed for safe, efficient, and organized electrical power distribution in industrial and commercial electrical systems. It is specially engineered for applications where one incoming power connection needs to be distributed to multiple outgoing circuits in a secure and compact manner. This distribution terminal block is widely used in electrical control panels, switchgear assemblies, automation systems, machine control panels, power distribution boards, OEM electrical installations, and industrial wiring systems where reliable multi-point power distribution is required. The unique design of the CDB4/3(1) makes it ideal for simplified power distribution inside electrical enclosures while reducing wiring complexity and improving panel organization.

In modern electrical systems, power distribution often requires splitting one incoming power source into multiple outgoing circuits. Using individual wires for such connections can make panel wiring complicated, time-consuming, and difficult to maintain. The CDB4/3(1) Distribution Terminal Block solves this issue by providing a central distribution point that allows a single incoming connection to be safely divided into 8 output connections of 4 sq.mm, creating a neat, compact, and professional wiring arrangement. This reduces installation time, improves safety, and simplifies future maintenance work.

The CDB4/3(1) features 1 x 16 sq.mm input connection with bolt type terminal and 8 x 4 sq.mm output screw clamp connections, making it suitable for power distribution applications where multiple branch circuits need to be fed from one source. The input connection is positioned at one end of the block instead of the center, which makes it highly suitable for specific panel layouts where end-entry wiring is preferred. This design improves cable routing and provides better wiring convenience in compact electrical panels.

One of the major advantages of the CDB4/3(1) Distribution Terminal Block is its ability to simplify panel wiring while maintaining electrical safety. The internally connected output terminals provide common electrical continuity, allowing incoming power to be distributed efficiently across multiple outgoing circuits. This reduces the need for multiple jumper wires and complicated wiring arrangements, improving overall panel aesthetics and maintenance efficiency.

The terminal block is rated for 800V AC/DC and supports 64A rated input current, making it suitable for industrial power distribution applications. The maximum individual output current is 64A (IEC), ensuring reliable electrical continuity for branch circuit distribution under industrial operating conditions. These ratings make the product suitable for power distribution circuits, automation systems, industrial machines, control panels, and commercial electrical installations.

The screw clamp output connection system ensures secure conductor fastening and long-term electrical reliability. Screw clamp technology provides strong wire retention, low contact resistance, and vibration-resistant electrical contact. This reduces the risk of loose connections, overheating, or electrical failure in industrial environments where machinery vibration and continuous operation are common. The bolt type input connection further provides secure incoming cable fastening for safe high-current power distribution.

Another key advantage of the CDB4/3(1) Distribution Terminal Block is its compact DIN rail mounting design. It can be easily installed on DIN 32 / DIN 35 / DIN 35-15 rails, making it compatible with standard electrical panel building systems. DIN rail mounting helps panel builders create organized and professional wiring layouts while reducing installation time. The compact modular construction also saves valuable panel space and improves service accessibility.

The terminal block is built using durable polyamide insulated housing, which offers excellent electrical insulation, mechanical strength, heat resistance, and flame retardant properties. The insulated body ensures safe conductor separation and protects users from accidental contact inside electrical enclosures. A protective shield effectively covers the incoming connection point, improving safety and reducing accidental contact risks during operation and maintenance.

The product also provides 8KV surge voltage resistance and pollution degree 3, ensuring reliable performance in industrial environments where electrical disturbances, moisture, dust, and harsh operating conditions may be present. These features improve overall electrical safety and long-term operational reliability.

The CDB4/3(1) Distribution Terminal Block is widely used in electrical control panels, industrial automation systems, machine control cabinets, switchgear panels, power distribution boards, renewable energy systems, OEM panel manufacturing, and industrial machinery wiring applications where organized and reliable power distribution is essential. It is a trusted solution for electricians, automation engineers, switchgear manufacturers, and panel builders who require compact and efficient multi-circuit power distribution inside electrical panels.

Whether used in industrial electrical systems, machine control panels, automation systems, or commercial power distribution boards, the CDB4/3(1) Distribution Terminal Block provides reliable power distribution, secure conductor connection, compact DIN rail mounting, and long-term electrical safety for modern panel building applications.
