This article describes the features of the IEC Appliance Plug C15 for cable mounting, including rewireable plug, 120°C pin temperature, and protection class I. It also provides detailed information on technical data and dimensions.
The 4781 appliance coupler is a rewireable IEC C15 plug designed for cable mounting with a pin temperature rating of 120 °C. It complies with IEC/EN 60320‑1 and UL/CSA standards, making it suitable for appliances requiring protection class compliance.
Key specifications include IEC ratings of 10 A / 250 VAC at 50 Hz, UL/CSA ratings of 15 A / 250 VAC at 60 Hz, dielectric strength over 2 kVAC, and operation temperatures from –25 °C to 120 °C. The black thermoplastic housing measures 28.7 mm in length, supports cable diameters up to 8.5 mm (or 10.0 mm for the larger variant), and requires specific torque settings for screws.
