Low-Loss Energy Saving and Convenient Adaptation of ZCEBOX Low-Voltage Junction Boxes

ZCEBOX low-voltage junction box (AC 220V/380V) strictly complies with GB 7251 and IEC 60439 standards, focusing on low-loss energy saving and full-scenario convenient adaptation. It is widely used in civil outdoor lighting, indoor power distribution (living room, study) and general industrial (small motors, auxiliary control circuits) scenarios, balancing energy saving, stability and practicality. The material adopts energy-saving modified flame-retardant PP+glass fiber composite material, which not only has the core characteristics of UL94 V-0 flame retardancy, low smoke and halogen-free (smoke toxicity grade FT2), temperature resistance of -30℃~110℃, and corrosion resistance of ISO 12944 C3+ grade, but also reduces its own dielectric loss through material formula optimization. Combined with low-resistance terminal design, it greatly reduces the loss during power transmission and can effectively reduce power distribution energy consumption after long-term use.

In terms of protection and connection, the IP65 protection adopts a combination of anti-aging silicone sealing ring and adaptive sealing plug, which can flexibly adapt to 0.75-10.0mm² single-strand hard wires and multi-strand flexible wires without additional adaptation accessories. It is tightly sealed after plugging and unplugging, effectively blocking water, dust and slight oil contamination; a built-in high-efficiency moisture absorption module (moisture absorption capacity ≥35g/100cm³) can quickly absorb condensed water, prevent terminal oxidation and corrosion, and extend service life. The terminals adopt silver-plated red copper low-loss design, with current capacity ≥45A and contact resistance ≤1.5mΩ, paired with anti-loose self-locking shrapnel for stable connection in vibrating environments. At the same time, a built-in insulation partition effectively avoids strong and weak current interference and ensures power distribution safety. For installation, it supports wall-mounted and embedded dual modes, with adjustable mounting holes reserved on the back to adapt to walls of different thicknesses. With an overall weight of ≤330g, it can be quickly installed by one person; for O&M, a detachable terminal block design is adopted, and the terminal block can be directly removed during maintenance without disassembling the box and cables. The box surface is laser-etched with clear voltage and terminal marks, combined with insulation warning lines, effectively avoiding maintenance misoperations and improving O&M convenience and safety.
