Thomas Betts 54213 Rectangle Ring Terminal 3/8 Stud Crimp

Product Description

The THOMAS BETTS 54213 is a non-insulated rectangle ring terminal designed for crimp-style electrical connections in professional wiring applications. It features a copper contact body with a titanium nitride (TiN) plating, which improves corrosion resistance and contact surface durability. The terminal measures 3.28 inches in overall length and 1.13 inches in ring width, with a material thickness of 0.14 inches. It accepts a 3/8-inch stud and is finished in yellow for visual identification during installation. Electricians and panel wiring technicians use this terminal in heavy-gauge termination work where a secure, low-resistance mechanical crimp is required.

The 54213 is suited for industrial control panels, power distribution assemblies, and equipment wiring where non-insulated ring terminals are the specified connection method. The rectangle ring geometry provides a larger bearing surface compared to standard round ring terminals, which helps distribute clamping force across the stud connection. This makes it a practical choice for applications where vibration resistance and secure mechanical retention are priorities. The yellow color coding aids in wire gauge sorting and circuit tracing during panel assembly and service work.

Key Features

• Non-insulated rectangle ring design with 3/8-inch stud size for positive mechanical retention
• Copper contact material with TiN plating for improved corrosion resistance and surface conductivity
• Crimp connection type for fast, reliable termination without soldering
• Overall length of 3.28 inches and ring width of 1.13 inches for a generous seating surface
• Material thickness of 0.14 inches for structural rigidity under torque load
• Yellow color for wire gauge identification and circuit organization
• CSA Certified, UL Listed (UL File E9809), and RoHS Compliant

Compatibility

Designed as a crimp-style ring terminal for use with 3/8-inch studs in non-insulated terminal applications across industrial control, power distribution, and equipment wiring installations.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lockout/tagout the circuit before terminating or inspecting any connections. Use a calibrated ratcheting crimp tool rated for the terminal and wire gauge being terminated to ensure a proper mechanical and electrical crimp. Do not substitute soldering for the crimp connection on this terminal type, as an improper termination can result in increased resistance or connection failure.
