The CDB4/2 Modular Distribution Terminal Block is a compact and efficient electrical distribution block designed for safe power distribution in industrial control panels, switchgear assemblies, automation systems, electrical cabinets, and OEM panel-building applications. It is specifically engineered to simplify wiring by providing a central input connection with multiple output terminals, allowing organized and secure power distribution from one source to several outgoing circuits. This makes it an ideal solution for modern industrial electrical installations requiring compact, reliable, and efficient current distribution.
The CDB4/2 belongs to Connectwell’s modular distribution block series and features 1 input connection with 8 output connections of 4 sq.mm, making it highly suitable for branch circuit distribution applications. A bolt-type central input connection ensures strong and secure incoming cable termination, while internally connected output terminals provide easy outgoing wire distribution without the need for complex jumper arrangements. This simplifies installation and improves wiring neatness inside control panels.
Designed for industrial electrical performance, the CDB4/2 offers a rated voltage of 800V, input current rating of 64A, and output current rating of 32A, ensuring dependable power distribution across multiple circuits. This makes it suitable for industrial machinery, automation panels, distribution boards, PLC panels, switchgear, and machine control systems where multiple outgoing power connections are required from a single incoming supply.
The terminal block is manufactured using high-grade polyamide housing, providing excellent insulation, flame resistance, mechanical durability, and long-term reliability under industrial operating conditions. A protective shield effectively covers the incoming connection, enhancing operator safety by reducing accidental contact risks during installation and maintenance. Its robust design ensures secure operation even in environments with vibration, thermal stress, and continuous electrical loading.
The CDB4/2 uses screw-type connection technology, allowing easy conductor termination using standard screw tightening methods. It features 2 Nm tightening torque on the input side and 0.5 Nm on the output side, ensuring secure conductor retention and reliable electrical contact. Its side-entry wire orientation improves wiring accessibility and allows organized cable routing inside electrical panels.
For mounting convenience, the CDB4/2 Modular Distribution Block is compatible with DIN 32, DIN 35, and DIN 35-15 rails, allowing quick integration into standard industrial control panel designs. Its compact footprint, safe protective construction, and multi-output power distribution capability make it an essential component for professionals seeking efficient branch power distribution in industrial and commercial electrical applications.
