The CDB4/2GN is a 4 sq.mm modular distribution terminal block in green colour, specially designed for protective earth (ground) distribution, common grounding circuits, and organized power distribution in industrial control panels, automation systems, switchgear assemblies, machine wiring, and electrical distribution boards. This terminal block provides a compact and reliable way to distribute one incoming electrical connection into multiple outgoing terminals, reducing panel wiring complexity and improving circuit organization.
In industrial electrical systems, grounding and power distribution circuits often require multiple outgoing connections from a single supply point. Traditional wiring methods using loop wires can create cluttered panel layouts and make troubleshooting difficult. The CDB4/2GN solves this issue by providing a central incoming connection with internally linked outgoing terminals, allowing safe and organized electrical distribution in a single compact unit. This reduces installation time and improves wiring efficiency inside control cabinets.
The green colour (GN variant) is commonly used for grounding / protective earth circuit identification in industrial electrical panels. Colour-coded terminal blocks make it easier for technicians and electricians to quickly identify circuit functions, improving safety during installation, inspection, and maintenance. In complex control systems, clear circuit identification helps reduce wiring errors and speeds up troubleshooting.
One of the major advantages of the CDB4/2GN 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 grounding or supply point needs to be distributed to multiple circuits. This is especially useful in automation panels, machine wiring systems, grounding bus arrangements, and industrial control cabinets.
The incoming connection is designed with a bolt-type central feed point, while the outgoing connections use secure screw clamp terminals for strong conductor retention and stable electrical continuity. This design ensures safe power transfer while minimizing loose connection risks and voltage losses in industrial applications.
Its compact DIN rail mounting design allows easy installation in industrial electrical enclosures while saving panel space. Instead of using several loop connections or separate distribution links, the CDB4/2GN centralizes distribution in a clean and organized terminal block format. This improves panel aesthetics and maintenance convenience.
Manufactured with high-grade polyamide insulated housing, the terminal block offers excellent heat resistance, electrical insulation, and mechanical durability for long-term industrial use. The protective housing also shrouds the incoming connection point, improving operator safety and reducing accidental contact risks during servicing.
The CDB4/2GN 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, grounding applications, machine panels, and automation wiring systems.
