CDB4/4 is a four-level feed-through terminal block engineered for industrial electrical systems where high connection density, space-saving panel wiring, and organized multi-circuit management are required. In PLC panels, switchboards, machine control systems, OEM electrical assemblies, and automation cabinets, several conductors often need to be terminated within limited DIN rail space. Traditional single-level terminals consume more panel space and create crowded wiring layouts.
The CDB4/4 is designed to overcome this challenge by offering four independent feed-through wiring levels within one compact terminal block, allowing panel builders to connect multiple circuits vertically rather than using additional DIN rail space. This improves wiring efficiency, reduces cabinet size, and supports professional electrical panel design.
It is especially suitable for high-density industrial control systems, where multiple signal, control, or power circuits need to be arranged in a compact and organized terminal assembly.
The CDB4/4 functions as a multi-tier feed-through wiring terminal, where conductors are connected through four separate electrical levels integrated inside one insulated terminal housing.
Its functional design allows:
The screw clamp conductor connection system securely locks each wire in place, ensuring dependable electrical contact and minimizing conductor loosening in industrial environments exposed to vibration and long operating cycles.
This design helps panel builders achieve maximum connection density while maintaining organized wiring access.
The CDB4/4 improves electrical panel safety by organizing multiple circuits in a structured and compact terminal arrangement.
Safety advantages include:
A structured multi-level terminal arrangement helps reduce maintenance mistakes and improves servicing efficiency.
The four-tier connection design provides several industrial wiring benefits.
Benefits include:
This makes the CDB4/4 highly effective for compact industrial electrical cabinets.
The CDB4/4 is manufactured using flame-retardant engineering polyamide insulation and industrial-grade conductive hardware, designed for demanding electrical environments.
Construction advantages include:
Its rugged industrial construction ensures dependable performance in control and automation systems.
Using CDB4/4 improves panel layout by combining multiple circuit connections into one compact terminal assembly.
