The Harmony Series 63A/4P-MXS3-A346-6 IP67 400V Industrial Plug is designed for three-phase four-wire electrical systems (L1 / L2 / L3 / N + Earth).
Its red IEC 60309 housing indicates a 400V rating, preventing mismatched voltage connections.
With an IP67 protection rating, the plug provides reliable performance in harsh environments including dust, rain, humidity, water spray, and temporary immersion.
It is ideal for construction sites, industrial machinery, mobile generators, port equipment, and event power distribution.
The flame-retardant PA66 body ensures excellent impact resistance, while nickel-plated copper contacts deliver stable conductivity and minimized temperature rise.
