CDB4/3Y is a 3-level feed-through terminal block in yellow color, specially designed for industrial electrical systems where maximum wiring capacity in limited panel space is required. In modern control panels, automation systems, PLC cabinets, and switchboards, multiple circuits often need to be connected in a compact area. Using standard single-level terminals can occupy more DIN rail space and make panel wiring crowded.
The CDB4/3Y solves this challenge by integrating three independent wiring levels in a single compact terminal block, allowing electricians and panel builders to connect multiple circuits efficiently while saving panel space. This makes it ideal for compact electrical cabinets, industrial automation systems, machine control panels, and OEM electrical assemblies where organized wiring and high-density connections are essential.
Its yellow housing color provides an added advantage for circuit identification. It is commonly used for warning circuits, dedicated signal lines, special control circuits, or phase identification, helping maintenance engineers quickly recognize specific wiring sections during servicing and troubleshooting.
The CDB4/3Y works as a multi-tier feed-through connection terminal, where conductors can be connected on three separate levels within one body. Each level provides an independent feed-through electrical path, allowing multiple circuits to be arranged vertically instead of spreading across more DIN rail space.
The screw clamp connection system ensures that conductors are securely clamped, creating stable electrical continuity and strong mechanical wire holding.
This design provides:
The yellow body color of the CDB4/3Y helps technicians quickly identify dedicated circuits inside electrical panels.
Safety advantages include:
Color-coded terminals make electrical servicing safer and reduce the risk of wrong circuit handling.
Yellow terminal blocks are commonly used in industrial applications where special circuits need visual separation.
Benefits include:
The CDB4/3Y is manufactured using flame-retardant engineering polyamide insulation, designed for industrial environments where electrical components are exposed to heat, vibration, and continuous operation.
Construction advantages include:
Using CDB4/3Y improves panel layout by allowing multiple wiring circuits in one compact terminal body.
