4-Way H Junction Box IP68

The BONAEVER junction box provides a four-way H-configuration for outdoor electrical connections. It accepts cables from 5-12mm in diameter with cross-sectional areas of 0.5-6.0mm². Rated for 40A and 450V, the PA66 nylon enclosure suits street lights, garden lights and buried luminaires.

IP68 Sealing and Temperature Range

Integrated injection moulding achieves an IP68 rating verified by a 4-metre water column test lasting 120 hours. Two sets of silicone sealing pads cover the 5-9mm and 9-12mm cable ranges. The housing operates continuously from -40 to 105 degrees Celsius with flame-retardant and UV-resistant properties.

Sustained Load Performance

Under continuous 40A loading the PA66 body maintains structural integrity across the full -40 to 105 degree range. The four-terminal wiring board and dual silicone seals preserve the IP68 barrier without degradation during prolonged immersion or thermal cycling.

Questions about this item

How do I install the BONAEVER 4-Way H junction box and which silicone pad set do I use?

Strip cables to 0.5-6.0mm² cross-section, match the external diameter 5-12mm to the correct pad set (5-9mm or 9-12mm), insert through the gland, tighten the compression nut until the silicone seals evenly, then secure the lid screws to maintain the IP68 rating.

What maintenance or replacement will the BONAEVER IP68 junction box need over time?

Inspect the two silicone pad sets and the PA66 nylon body annually for UV degradation, cracking, or compression set; replace any seal that no longer springs back or shows surface crazing to keep the IP68 seal intact.

What is the first limit reached on the BONAEVER 4-Way H box during sustained high-load use?

The 40A rated current of the internal wiring board is the primary limit; exceeding it causes conductor heating above the 105°C maximum working temperature before the PA66 housing or IP68 seal becomes a factor.
