CDB4/4BK is a four-level feed through terminal block in black color designed for industrial electrical systems where high-density wiring, multiple circuit termination, compact panel installation, and structured conductor management are essential. In electrical control panels, PLC cabinets, industrial automation systems, machine control assemblies, and switchboards, engineers often need to terminate several circuits in a limited DIN rail space. Using standard single-level terminals in such installations increases panel size, creates wiring congestion, and reduces maintenance efficiency.
The CDB4/4BK solves this problem by integrating four independent feed through wiring levels in one compact terminal body, allowing multiple conductors to be connected vertically instead of using separate individual terminals. This improves wiring density, reduces DIN rail consumption, and supports better circuit management in compact electrical cabinets.
The black housing also provides an additional advantage for dedicated circuit grouping, visual section separation, and organized panel wiring identification, making maintenance and troubleshooting easier in industrial applications.
This terminal block is an ideal solution for panel builders who need space optimization, structured multi-circuit wiring, and reliable conductor connection performance in industrial electrical systems.
The CDB4/4BK works as a four-level feed through terminal block, allowing conductors to be connected through four separate electrical levels inside one insulated terminal body.
Its functional design provides:
The screw clamp conductor connection mechanism securely locks each wire and ensures reliable electrical continuity. This helps reduce conductor loosening and supports stable current transfer in industrial electrical systems.
Its four-level vertical design makes it highly effective for compact high-density panel wiring applications.
The black housing color improves visual circuit grouping and panel section recognition.
Safety advantages include:
Color-based terminal grouping improves wiring management in industrial panels.
Black terminal blocks are commonly used for:
This helps create structured and professional electrical panel designs.
The CDB4/4BK is manufactured using flame-retardant engineering polyamide insulation with industrial-grade conductive terminal hardware, designed for industrial electrical environments.
Construction advantages include:
Its rugged construction ensures dependable performance in demanding industrial electrical systems.
Using CDB4/4BK improves electrical panel layout by combining multiple conductor circuits into one compact terminal block.
