CDB4/4Y is a four-level feed through terminal block in yellow color specially designed for industrial electrical systems where high-density conductor termination, compact DIN rail wiring, multi-circuit distribution, and visual circuit grouping are required. In electrical control panels, PLC cabinets, switchboards, machine control systems, industrial automation assemblies, and instrumentation panels, engineers often need to connect multiple conductors in a limited wiring space while maintaining clear circuit organization.
Using standard single-level terminal blocks in such applications increases panel space requirements and creates wiring congestion. The CDB4/4Y solves this challenge by integrating four independent feed through connection levels in one compact insulated terminal body, allowing multiple circuits to be connected vertically in a single terminal assembly.
The yellow housing offers a strong visual identification advantage and is commonly used in industrial panels for special circuit grouping, caution circuit identification, maintenance reference sections, and dedicated terminal section marking, helping technicians identify important terminal groups quickly.
This terminal block is ideal for industrial applications where space-saving wiring, secure conductor retention, and organized multi-circuit management are critical.
The CDB4/4Y operates as a four-level feed through terminal block, where conductors are connected through four independent electrical paths integrated inside one compact terminal body.
Its working design provides:
The screw clamp connection system securely locks conductors and creates dependable electrical continuity, ensuring stable current transfer and reliable electrical performance.
Its four-level design makes it highly suitable for compact industrial panel wiring applications.
The yellow housing color improves visual recognition of dedicated terminal sections inside electrical panels.
Safety advantages include:
Color-coded terminal grouping improves panel safety and organization.
Yellow terminal blocks are commonly used for:
This supports structured electrical panel management.
The CDB4/4Y is manufactured using flame-retardant engineering polyamide insulation with industrial-grade conductive terminal hardware, designed for industrial electrical environments.
