Summary

• Lot of 10 WAGO 281 Series 3-conductor feed-through terminal blocks, consisting of 7 gray and 3 blue terminal blocks, including 1 WAGO 281-324 gray end plate.
• These 4mm² DIN rail terminal blocks feature WAGO CAGE CLAMP spring-pressure connection technology for secure and reliable electrical connections in industrial control panels, automation systems, and electrical distribution applications.
• The gray terminal blocks are WAGO 281-681 models. The blue terminal blocks are the corresponding blue-style 281 Series terminals. The included WAGO 281-324 end plate provides insulation and protection at the end of a terminal block assembly.
• This listing includes 10 WAGO terminal blocks (7 gray and 3 blue) and 1 WAGO 281-324 gray end plate only. No original box, instructions, manuals, DIN rail, wiring, or additional accessories are included.
• This item was sourced from a new, uncommissioned equipment cabinet that was dismantled prior to being placed into service.

Product Description

• The WAGO 281 Series 3-conductor feed-through terminal blocks are designed for dependable electrical connections in industrial control systems, automation cabinets, machinery, and power distribution equipment.
• Each terminal block features WAGO's CAGE CLAMP spring-pressure connection technology, which provides a secure, vibration-resistant electrical connection without traditional screw-clamp conductor termination.
• The 3-conductor configuration provides three connection points on a single electrical potential, allowing multiple conductors to be connected together within one compact terminal block.
• Designed for installation on standard 35mm DIN rails, these terminal blocks support conductor sizes up to 4mm² and feature center marking areas for convenient circuit identification.
• The included blue terminals provide color differentiation within the terminal assembly, while the gray WAGO 281-324 end plate provides electrical separation and insulation at an exposed end of the terminal block group.
• This 11-piece lot is suitable for constructing, expanding, or maintaining industrial electrical control panels and terminal strip assemblies.
