The WEIDMULLER 1806980000 is a ZDU 4-2/4AN series feed-through terminal block designed for organized, secure wire termination in industrial control panels and electrical enclosures. This type of terminal block provides a reliable connection point for branch circuit wiring, allowing conductors to be landed and distributed within a terminal strip assembly. Electricians and panel builders use this component when building or servicing industrial control cabinets, automation panels, and distribution boards where organized, code-compliant wiring is required.
The ZDU 4-2/4AN series terminal block is suited for use in industrial and commercial electrical installations. It is commonly installed in DIN rail-mounted terminal strip assemblies found in manufacturing facilities, process control systems, HVAC control panels, and building automation systems. Panel fabricators and licensed electricians specify this type of terminal block where multiple circuits require a common, organized termination point in a compact enclosure layout.
Designed as an OEM-style feed-through terminal block for use in DIN rail-mounted terminal strip assemblies in industrial and commercial control panel applications.
Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes. De-energize the panel completely and verify the absence of voltage with a meter before handling or installing terminal blocks. Secure the terminal block firmly onto the DIN rail before landing conductors, and ensure conductor sizing and torque are appropriate for the terminal rating.
