RS PRO Insulated Ring Terminal, Vinyl, 4.3 mm Stud, 22 - 16 AWG, Red, 1.5 mm² Max E245391 178-7266

The RS PRO 178-7266 E245391 Insulated Ring Terminal is specifically engineered to provide reliable connection integrity for electrical and electronic wiring tasks where secure fastening and insulation are critical. Manufactured with a high-quality copper contact and a red vinyl insulation sleeve, this ring terminal supports easy identification and optimal performance across a range of electrical environments.

This ring terminal is compatible with wire sizes from 22 AWG to 16 AWG, or up to 1.5 mm² in cross-sectional area, offering flexibility across many typical installation settings within control panels, automation systems, automotive harnesses, and general industrial applications. The inner ring diameter is precisely 4.3 mm, designed to fit common stud sizes found in industrial and electronic equipment. The outer ring measures 8 mm for a solid mechanical bond. Vinyl insulation provides added protection during handling and service, reducing risk of accidental electrical contact and improving worker safety. The strong copper base material is plated with tin, guarding against oxidation and ensuring low-resistance electrical flow.

Operating reliably in temperature extremes from -40°C to +105°C, this terminal is ideally suited for challenging environments and consistent, long-life service. The vivid red color of the insulation sleeve enables fast and accurate identification of compatible wire gauges during installation and maintenance, reducing wiring errors and speeding up workflow. With a convenient overall length of 21 mm, the terminal fits readily into tight spaces found in junction boxes, terminal strips, and modular equipment connections.

This insulated ring terminal is suitable for use in a broad spectrum of commercial and industrial projects. Its robust construction and precise engineering make it a preferred choice for panel builders, machinery maintenance engineers, wiring contractors, and electronics installers requiring dependable power or signal terminations.

The RS PRO E245391 series ensures safe and efficient electrical connections in industrial control panels, machinery, HVAC systems, building automation, automotive wiring, low-voltage power distribution, and wherever color-coded and size-matched wire termination is essential for quality and operational safety.
