ZCEBOX LWHC Series: Advanced IP66 Distribution Boxes for High-Reliability Electrical Systems

The ZCEBOX LWHC Series Distribution Box (AC 220V/380V) is engineered for elite residential, commercial, and industrial power management where reliability is non-negotiable. Strictly adhering to GB 7251 and IEC 60439 standards, this series supports versatile configurations from 4 to 36 modules, making it the ideal housing for MCBs, RCCBs, and other critical DIN-rail components. The enclosure is crafted from high-toughness modified Polycarbonate (PC), which offers a fire resistance rating of 850°C/30s and an impact strength of IK08+. Designed to operate in expanded temperature ranges from -35°C to 115°C, the LWHC series ensures no aging, embrittlement, or deformation under severe solar UV exposure, high humidity, or industrial dust erosion, meeting ISO 12944 C3+ corrosion resistance criteria.

Internal stability and protection are the cornerstones of the LWHC series. The box features an IP66 fully sealed design with an integrally formed silicone gasket and waterproof sealing plugs to block splashing water and oil contamination completely. The electrical performance is fully upgraded with built-in silver-plated red copper terminal bars (current capacity ≥48A, contact resistance ≤1.2mΩ) and pre-installed high-strength aluminum DIN rails. Weighing ≤320g (for standard units), the LWHC supports both surface-mounted and wall-embedded installations with reserved precise positioning holes for 1-2 minute single-person setup. The quick-release transparent PC door and laser-etched wear-resistant markings balance industrial maintenance convenience with aesthetic appeal.
