CDB4/4R is a four-level feed through terminal block in red color designed for industrial electrical systems where high-density conductor termination, multi-circuit distribution, compact DIN rail installation, and dedicated circuit grouping are required. In electrical control panels, PLC cabinets, switchboards, industrial automation systems, machine control assemblies, and instrumentation panels, engineers often need to connect multiple conductors in limited panel space while maintaining clear wiring organization.
Using standard single-level terminals for such applications increases DIN rail usage, creates panel congestion, and makes maintenance more difficult. The CDB4/4R solves this problem by integrating four independent feed through connection levels in one compact insulated terminal body, allowing multiple conductors to be connected vertically in a single terminal assembly.
The red housing offers a visual identification advantage and is commonly used in industrial electrical panels for warning circuits, emergency control sections, dedicated power lines, and critical circuit grouping, helping technicians identify important terminal sections quickly during maintenance and servicing.
This terminal block is ideal for industrial applications where space-saving wiring, secure conductor retention, and organized multi-circuit management are essential.
The CDB4/4R 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 industrial electrical performance.
Its multi-level design makes it highly effective for compact high-density wiring applications.
The red housing color improves visual recognition of warning or critical terminal sections inside electrical panels.
