CMDB4/10 Modular Distribution Terminal Block is used for safe and organized electrical power distribution in industrial control panels, switchgear systems, automation cabinets, and electrical distribution applications. It allows one incoming power source to be distributed across multiple outgoing terminal points, reducing complex jumper wiring and creating a compact, structured power distribution system. This modular distribution block is ideal for applications where safe branch power distribution, compact DIN rail installation, and organized panel wiring are required.
CMDB4/10 works as a 4 sq.mm modular distribution block with 20 output connections (10 each side) that allows one electrical input to distribute power safely to multiple outgoing circuits. The internal conductive current bar ensures reliable electrical continuity between all connected terminals, while the screw clamp connection system provides secure conductor holding and low contact resistance. This design improves power distribution efficiency, reduces wiring complexity, and creates a safer electrical distribution point in industrial panels.
CMDB4/10 improves electrical safety by creating a structured and insulated distribution point inside industrial panels. Instead of multiple loose wire branching connections, it provides a centralized and organized power distribution arrangement. This improves circuit identification, reduces accidental wiring errors, and enhances operator safety during maintenance and troubleshooting.
CMDB4/10 is manufactured using high-grade Polyamide insulated housing that provides strong mechanical durability, flame resistance, and excellent electrical insulation performance. Its M3 screw clamp connection system ensures secure wire holding and vibration-resistant performance, while the internal conductive current bar provides efficient low resistance current transfer for industrial electrical applications.
Using CMDB4/10 improves panel wiring by replacing multiple separate jumper wire arrangements with one compact modular distribution block. This reduces panel clutter, saves installation time, improves maintenance access, and creates a cleaner and more professional electrical panel layout. DIN rail mounting also helps optimize panel space in industrial power distribution systems.
