Thomas Betts 54510 Non-insulated Butt Splice Terminal

Product Description

The THOMAS BETTS 54510 is a non-insulated, crimp-on butt splice terminal designed to create a secure inline connection between two wire ends in electrical wiring applications. Constructed from copper with a tin nitride (TiN) contact plating, the 54510 provides reliable conductivity and corrosion resistance in demanding service environments. At 1.75 inches overall length and 0.57 inches overall diameter, it is a compact splice that accommodates two wire entries for straightforward inline termination. Electricians and electrical contractors install this type of terminal when joining conductors without the bulk of an insulated sleeve, leaving the splice accessible for inspection or heat-shrink finishing.

The 54510 is suited for residential, commercial, and light industrial wiring tasks where a clean, low-profile crimp splice is required. It is commonly used in control wiring, panel wiring, and equipment harness repair. The non-insulated design makes it compatible with follow-on insulation steps such as heat-shrink tubing. This terminal meets CSA, UL Listed (File Y), and RoHS compliance requirements, making it appropriate for regulated installations across North American jurisdictions.

Key Features

• Non-insulated crimp-on design for inline wire-to-wire splicing with two wire entries
• Copper contact material with TiN plating for conductivity and corrosion resistance
• Compact form factor: 1.75 inches overall length, 0.57 inches overall diameter
• CSA Certified, UL Listed (File Y), and RoHS Compliant
• Black color finish for easy field identification

Compatibility

Designed as an OEM-style crimp splice terminal for use in standard electrical wiring and control circuit applications requiring a non-insulated inline butt connection.

Installation Notes

Installation of butt splice terminals is performed by licensed electricians in accordance with NEC requirements. De-energize and lock out the circuit before terminating any conductors. Use a calibrated ratcheting crimp tool rated for non-insulated terminals to achieve a proper mechanical and electrical connection. Avoid over-stripping conductors, and apply heat-shrink tubing or approved insulation over the completed splice as required by code or application.
