Core Advantages of Multifunctional Adaptation and Long-Term Stability of ZCEBOX Low-Voltage Junction Boxes

ZCEBOX low-voltage junction box (AC 220V/380V) strictly complies with GB 7251 and IEC 60439 standards, with core design focusing on multifunctional adaptation and long-term stability, covering all scenarios of civil use (residential buildings, commercial buildings, outdoor auxiliary facilities) and general industry (ordinary workshops, small machine rooms, auxiliary power equipment). The material adopts high-rigidity modified flame-retardant PP+glass fiber reinforced composite material, featuring UL94 V-0 flame retardancy, low smoke and halogen-free properties, and smoke toxicity grade up to FT2 standard. The temperature resistance range is expanded to -30℃~110℃, and the corrosion resistance grade is upgraded to ISO 12944 C3+ level, which can withstand civil outdoor temperature differences, high humidity in basements, and slight industrial oil contamination and dust erosion, without aging or embrittlement after long-term use.

The built-in silver-plated red copper terminals are upgraded to a high current-carrying design (current capacity ≥38A, contact resistance ≤2.5mΩ), paired with double-layer anti-loose shrapnel, ensuring zero loose connection in vibrating environments and adapting to 1.0-8.0mm² wide-specification low-voltage cables. IP65 protection grade is combined with "integrally formed silicone sealing ring + double-layer elastic sealing plug" to fully block water and dust; a built-in large-capacity moisture absorption module (moisture absorption capacity ≥30g/100cm³) effectively inhibits the generation of condensed water and eliminates terminal oxidation and corrosion. In terms of installation, it supports three mounting modes: wall-mounted, embedded and ceiling-mounted. The ultra-light design (≤360g) combined with precise positioning holes allows one person to complete installation in 3 minutes; the quick-release buckle + pull-out terminal block enables maintenance without disassembling cables, and the laser-etched multilingual marks are clear and wear-resistant, greatly reducing the operation and maintenance difficulty and cost in all scenarios.
