WEIPU WH400A IP67 Series is a 400A heavy-duty single-pole power connector built for high-current power transmission in outdoor and harsh industrial environments. It combines an IP67 waterproof rating with a bayonet-locking coupling to deliver a fast, secure connection that stays stable under vibration.

Designed for safety and long service life, the WH400A uses a rugged, flame-retardant (UL94-V0) housing and color-coded, mechanically keyed alignment to prevent incorrect mating and reduce installation errors. Silver-plated brass contacts help minimize contact resistance, support consistent conductivity, and improve corrosion durability.
