The Harmony Series 63A/4P-MXS3-A344-6 IP44 400V Industrial Plug is designed for medium to heavy-duty three-phase four-wire systems (L1, L2, L3 + N).
Its red housing complies with IEC 60309 coding for 400V, ensuring correct voltage matching and preventing connection errors.
With an IP44 splash-proof and dust-resistant rating, the A344-6 is ideal for workshops, industrial power distribution, and construction sites.
The plug features a flame-retardant PA66 housing and nickel-plated copper contacts, providing excellent durability, reduced heating, and stable conductivity.
A reinforced cable gland enhances strain relief, making the plug suitable for environments with frequent movement or vibration.
