Weidmuller WDU 1.5/ZZ Feed-Through Terminal Block Description

Functions

Provides electrical connection point for wire termination and feed-through capability in control panels and distribution systems. Features screw-clamp technology for secure conductor attachment, accommodates wire sizes up to 1.5mm², enables tool-free jumpering between adjacent terminals via continuous internal bus bar. Offers test point access for circuit verification without disconnecting wires. Mounts on standard 35mm DIN rail, interfaces with marking tags and accessories for circuit identification. Commonly used in industrial control cabinets, PLC I/O wiring, signal distribution, and power distribution applications requiring organized wire management and reliable electrical connections.

Platforms

DIN rail mounting system for industrial control panels and electrical enclosures, compatible with 35mm top-hat rails conforming to EN 60715 standard. Spring-cage or screw-type connection technology for 26-14 AWG conductors. Modular terminal block architecture allowing side-by-side assembly with bridging accessories for common potential distribution. Operating temperature range -60°C to +130°C for harsh industrial environments. 600V rated insulation voltage for power distribution and control circuit applications. Tool-free wire insertion with push-in technology or standard screwdriver termination. Compatible with end plates, partition plates, marking systems, test plugs, and cross-connection jumpers for system expansion.

Applications

Designed for use in electrical control cabinets and distribution systems, this feed-through terminal block allows secure screw connection of conductors up to 1.5 mm² cross section, facilitating the transmission of electrical signals or power between wiring segments. It supports industrial voltage ratings up to 800 V and currents up to 17.5 A, making it suitable for signal, control, and power wiring in automation, machinery, panel building, and industrial process control environments. Its compact design enables efficient DIN rail mounting and straightforward integration with plug-in connectors and other terminal blocks in modular electrical assemblies.

Accessories

DIN rail mounting, end brackets, jumper bars, test plugs, potential distribution blocks, marking strips, wire ferrules for 1.5mm² conductors. Requires 35mm DIN rail. Compatible with ZDU bridge connectors for potential distribution. Test point accessible with 2mm test probes. Wire entry accepts solid or stranded conductors 0.2-1.5mm² (AWG 24-16). Screw terminal with slotted head accepts 3.5mm screwdriver. Operating temperature -60°C to +100°C.

Interfaces

Spring-cage connection technology with tool-free wire insertion for solid and stranded conductors 0.2-1.5 mm² (AWG 24-16). Push-in connection mechanism eliminates need for screwdrivers or ferrules. Single-level 5.2mm width terminal suitable for DIN 35 rail mounting. Direct plug-in connection to adjacent terminals. Test point access via 2mm test probe opening. Wire release via integrated actuator button.

Specifications

Designed for secure, reliable electrical connections in control cabinets and distribution boards, this feed-through terminal block supports conductor cross-sections up to 1.5 mm², operating within a voltage range suitable for industrial automation systems. It features a compact modular design compatible with standard DIN rail mounting, enabling easy integration and expansion within electrical panels. The terminal block employs screw clamp technology for efficient wire termination and a clear polycarbonate housing for visual inspection, interfacing seamlessly with other terminal blocks and auxiliary components in complex wiring assemblies.
