Terminal Block 26 10 Awg? Single Level Feed Through Black · Eaton XBUT4BK

What this product is for

The Eaton XBUT4BK is a single-level feed-through terminal block for terminating and joining conductors on DIN rail in industrial and commercial control panels. It is used where electricians and panel builders need an organized, serviceable wiring point for copper conductors from 26-10 AWG.

Use for

Use for panel wiring, machine control cabinets, marshalling points, and distribution assemblies that require screw connection terminations. The 6.2 mm (about 0.24 in) width helps when panel space is limited.

Avoid for

Avoid for applications that need fused protection, disconnect functionality, or multi-level circuit separation in one block. Also avoid assuming accessory compatibility without checking the matching XB series parts.

Best for

Best for electricians, OEM panel shops, and maintenance teams standardizing on DIN rail terminal blocks for straightforward feed-through connections. The black housing can also help with circuit identification where colour coding is part of the panel layout.

Installed in

Typically installed in industrial control panels, commercial equipment panels, OEM machinery, and electrical enclosures using standard DIN rail layouts.

Why this product exists

This product provides a compact, code-recognized termination point that is easier to service than free-air splices or ad hoc terminations inside an enclosure. It supports cleaner panel layout, easier troubleshooting, and more consistent wire management.

Compared with similar products

Compared with double-level or disconnect terminal blocks, this is a simpler single-level feed-through style for direct conductor-to-conductor termination. It is a better fit when you want a standard pass-through connection without added fuse or knife-disconnect features.
