Junction Box 3 Way IP68 Outdoor

The BONAEVER junction box is a three-way electrical enclosure rated IP68 for continuous immersion at four metres for one hundred twenty hours. It accepts one incoming cable and splits to two outgoing connections using the supplied four-position terminal block. The PA66 housing with silicone seals resists UV, corrosion and high temperatures for long-term outdoor service.

Terminal Block 40A 450V AC

The included terminal block is rated for forty amperes at four hundred fifty volts AC and accommodates conductor cross-sections from zero point five to six square millimetres. Three sets of waterproof rubber rings cover cable diameters from five to fourteen millimetres in overlapping ranges. This specification determines whether the box suits the circuit current and cable size in the installation.

Sealed Enclosure Sustained Load

Under continuous load the copper screw terminals maintain stable contact while the PA66 body and silicone gaskets retain their seal at depth. The housing does not crack or fade under prolonged sunlight and the ingress protection remains effective during extended submersion. Installers who need a higher current rating or more than three poles will require a different enclosure.

Questions about this item

How much current can the terminal block handle once it is installed in a real circuit?

The four-position terminal block is rated for 40A at AC 450V, so it will carry up to 40 amps continuously when wired correctly.

What does the IP68 rating actually limit in everyday outdoor use?

IP68 (IPX8: 4M, 120H) means the box is dust-tight and can stay submerged at 4 metres depth for 120 hours, so it handles permanent outdoor exposure, burial or temporary flooding.

What size mounting holes or fixings does the box need to be secured?

The package includes four nails for mounting; the housing measures 71 x 56 x 29.3 mm externally, so you only need a surface that can accept those nails or equivalent screws.
