Thomas Betts 54512 Non-insulated Butt Splice Terminal

Product Description

The THOMAS BETTS 54512 is a non-insulated, crimp-on butt splice terminal designed to join two wire ends in a single inline connection. Constructed from copper with a titanium nitride (TiN) contact plating, this terminal delivers reliable conductivity and corrosion resistance in electrical splicing applications. It measures 1.88 inches in overall length and 0.70 inches in overall diameter. The non-insulated design requires separate sleeving or heat shrink if insulation is needed at the splice point. It is installed by electricians and electrical contractors working on control wiring, panel builds, and field splicing tasks.

This butt splice terminal is suited for residential, commercial, and light industrial electrical work where a compact inline crimp connection is required. Its two-entry configuration accepts one wire from each end, making it appropriate for straight wire splices in control circuits, appliance wiring, and panel harnesses. The purple color coding aids in wire gauge identification during installation and inspection.

Key Features

• Non-insulated crimp-on design for fast, tool-based wire termination
• Copper contact material with TiN (titanium nitride) plating for conductivity and durability
• Two wire entries for standard inline butt splicing
• Overall length of 1.88 inches and overall diameter of 0.70 inches
• Purple color for wire gauge identification
• CSA Certified, UL Listed, and RoHS Compliant

Compatibility

Designed as an OEM-style crimp terminal for use in electrical control wiring, panel assembly, and field splicing applications where a non-insulated butt splice connection is required.

Installation Notes

Installation is performed by licensed electricians or qualified electrical technicians using a calibrated ratcheting crimp tool rated for the applicable wire gauge and terminal type. De-energize and lock out the circuit before splicing. Because this terminal is non-insulated, apply appropriate sleeving, heat shrink tubing, or electrical tape over the completed splice to meet NEC insulation requirements. Inspect the completed crimp for full conductor insertion and a secure mechanical hold before restoring power.
