Product Description
RS PRO 178-8625 Uninsulated Ring Terminal offers dependable connectivity for electrical and electronic wiring needs. Part of the E245391 series, this terminal is optimized for 8 AWG wires and features a 6.4 mm stud size, making it compatible with common panel and distribution hardware. Its uninsulated structure ensures direct metal contact and efficient heat dissipation during high-current applications.
The terminal is manufactured from high purity copper and finished with tin plating for excellent corrosion resistance. The inner ring diameter of 6.4 mm and outer diameter of 12 mm ensure strong mechanical fastening and reliable electrical performance. Grey colour coding assists in organizing and identifying connections within complex installations.
Supporting a maximum wire size of 8 AWG (8 mm²), the terminal allows secure crimping and robust electrical conductivity. Its 23.3 mm overall length and 1.2 mm thickness provide a balance between compact sizing and mechanical strength, ideal for cabinet, panel, automotive, and industrial machinery wiring.
Performance is stable across challenging environments, from -40°C minimum to 150°C maximum operating temperature. The uninsulated design permits use where insulation is not required, and crimping tools can access the copper body directly for optimal connection.
RS PRO terminals are commonly deployed in industrial, commercial, control panels, HVAC, and distribution boards, where reliable current carrying and clear terminal marking are needed.
For electrical engineers, installers, and maintenance teams, this ring terminal delivers durable, corrosion-resistant connectivity and fits standard 6.4 mm studs used in wiring blocks, terminal strips, and busbars.
