3-Way Y Junction Box IP68

The BONAEVER junction box provides a three-way Y connection with one input and two outputs rated at 40A and 450V. It accepts cable diameters from 5-12mm and cross-sectional areas of 0.5-6.0mm². The enclosure achieves IP68 protection tested at 4 metres water column for 120 hours. It operates across a temperature range of -40 to 105°C.

Integrated Injection Moulded Enclosure

The box uses integrated injection moulded PA66 nylon housing that delivers waterproof, dustproof, flame-retardant and UV resistant performance. Two sets of silicone sealing pads accommodate cables from 5-9mm and 9-12mm. External dimensions measure 4.84 by 3.22 by 1.65 inches with internal space of 2.79 by 2.2 by 1.14 inches. This construction suits outdoor lighting, street lights, buried lights and garden floodlights.

Sustained Environmental Sealing

Under continuous immersion the IP68 seal maintains integrity for the full 120-hour test duration at 4 metres depth. The PA66 material resists UV degradation and temperature cycling from -40 to 105°C without compromising the silicone gasket compression. Flame-retardant properties persist throughout extended operation. Installations needing more than two output branches or cables outside the 5-12mm range require a different enclosure design.
