The C-Form 3-Pin connector (complying with IEC 60309) is a heavy-duty, single-phase industrial plug and socket system designed to deliver safe, weather-resistant electrical power in demanding environments [Image 1, Image 3]. It features three large, robust pins (Live, Neutral, and Earth) and is most instantly recognizable by its distinct blue color-coded casing, which universally denotes a standard voltage range of 200V to 250V
Mechanical Keying & Polarization: Features a built-in safety notch (6h grounding clock position) that makes it physically impossible to mate plugs into mismatched voltages or incorrect polarities. Industrial Weatherproofing: Typically built to IP44 (splash-proof) or IP67 (completely waterproof) standards, protecting electrical contacts from dust, water ingress, and heavy physical impacts.
Color-Coded Standard: The bright blue casing immediately identifies it for 230V single-phase electrical mains
High-Amperage Options: Most commonly deployed in standard 16A and heavy-duty 32A configurations for continuous power flow 
Amusement & Stage Staple: Serving as the standard power hookup for outdoor catering trucks, festival sound stages, industrial workshops, and caravans
Shrouded Safety Pins: Engineered with thick, recessed brass pins that prevent accidental finger contact during insertion or removal
Locking Securing Cap: Designed with a spring-loaded socket lid that latches tightly onto the plug to prevent accidental disconnects from cable tension
