The Harmony Series 16A/4P-MXS3-A144-6 IP44 400V Industrial Plug is built according to the IEC 60309 international standard and designed for 400V three-phase applications with a 4-pole configuration.
The plug uses standardized red color coding, preventing mismatched connections across different voltage systems.
The housing is crafted from high-strength, flame-retardant PA engineering plastic, providing excellent impact resistance. The nickel-plated copper pins offer superior conductivity and long-term corrosion resistance.
With Harmony’s ergonomic design, the plug offers smoother insertion and extraction, while the integrated cable clamp ensures secure cable fastening.
The IP44 protection level makes it suitable for workshops, factories, warehouses, and other general industrial environments.
