| Eliminate maintenance blind spots while securing your core components. The BSUMWELL IP66 400×300×170mm Weatherproof Electrical Enclosure is a heavy-duty asset protection solution engineered for demanding solar, marine, and security environments. Unlike standard opaque metal boxes that rust and require labor-intensive manual opening for checks, this premium enclosure features an ultra-clear, high-tenacity polycarbonate cover providing full 360° visual monitoring of internal digital displays and relays. Security is paramount; it integrates a built-in mechanical lock to prevent unauthorized tampering or accidental shock exposure. Inside, a specialized insulated grid mounting plate (370×270×5mm) offers flexible, drill-free component configuration and superior electrical isolation. Constructed from premium, non-recycled grey-white engineered thermoplastic, the box achieves an exceptional strength-to-weight ratio (2.48kg net weight) and an IK08/IK10 impact rating. It seals tightly against high-pressure water jets and salt spray, guaranteeing your electronics remain dry, cool, and operational throughout intense environmental stress cycles. | |||||||||

With over 15 years of industry-leading B2B enclosure manufacturing, BSUMWELL understands the nuances of thermal dissipation and UV stability. Our clear-cover enclosures are specifically formulated to combat polymer yellowing and micro-cracking caused by prolonged solar radiation.
The internal grid mounting plate is manufactured using high-dielectric engineering materials to provide a physical anti-electric shock barrier. By replacing heavy steel mounting plates, we eliminate ground-fault risks while streamlining wall-mount installations.
Every 400x300x170mm distribution box undergoes rigorous vacuum-pressure sealing and automated drop tests to verify its IP66 and IK08 ratings, exceeding CE and IEC industrial infrastructure standards.
BSUMWELL – Clear Vision, Solid Protection. Our lockable transparent enclosures are globally trusted across industrial solar farms, coastal telecom setups, and municipal security systems. We offer comprehensive engineering specification sheets and localized technical support for global procurement.
