The CDB4/2BK is a 4 sq.mm modular distribution terminal block from Connectwell’s CDB series, specifically designed for safe power distribution and multiple outgoing electrical connections in industrial control panels, switchgear assemblies, automation systems, and electrical distribution boards. This model is the black colour variant of the CDB4/2 series and provides a compact, organized, and secure solution for distributing one incoming supply to multiple outgoing circuits.
The CDB4/2BK features 1 central input connection with 8 output terminals, making it ideal for electrical panels where multiple branch circuits need to be connected from a single power source. The incoming wire is connected through a central distribution point, while the internally shorted output terminals allow even and efficient power distribution to connected circuits. This reduces wiring complexity and eliminates the need for multiple loop connections inside control panels.
One of the biggest advantages of the CDB4/2BK is its compact DIN rail mounting design. In industrial panels where space is limited, traditional distribution methods can make wiring messy and difficult to maintain. This modular distribution block simplifies panel layout by centralizing power distribution in one compact unit. The result is cleaner wiring, easier maintenance, and improved troubleshooting.
The black housing (BK variant) helps with circuit colour identification, which is useful in electrical systems where different colour-coded circuits are required for safety, polarity indication, or system organization. Connectwell offers colour variants for professional panel building applications.
Manufactured with high-grade Polyamide insulating material, the CDB4/2BK offers excellent dielectric strength, heat resistance, and mechanical durability. The housing safely shrouds the incoming connection while protecting operators against accidental contact. Its screw clamp termination system ensures secure conductor retention, stable electrical contact, and long-term reliability in industrial environments.
The rated voltage is 800V IEC, with 64A input current capacity and 32A output current rating, making it suitable for industrial low-voltage distribution systems. It supports 4 sq.mm outgoing connections and is designed for DIN 32 / DIN 35 rail mounting.
