5-Pack IP68 Junction Boxes

This five-pack supplies M20 three-pole connectors rated for AC 400 V and 24 A. Each unit accepts cables from Ø5-9 mm or Ø9-12 mm using the two included rubber-ring sizes. The PA66 housing carries V-0 flame retardancy and operates from -40 °C to 105 °C with UL, TUV, SAA, CE and RoSH approvals. They suit outdoor lighting, signage and underwater installations down to 3.5 m depth.

Installation Ease and Common Pitfalls

A single screwdriver is all that is required to terminate live, neutral and earth conductors inside the compact housing. The dual-range rubber rings and clamping nuts create the IP68 seal, but the seal fails if any nut is left loose after assembly. Over-tightening can damage the cable jacket, while under-tightening lets moisture enter. Always verify every nut is snug before energising the circuit.

Sustained Load Behaviour

The V-0 rated PA66 body maintains structural integrity and sealing across the full -40 °C to 105 °C operating window during continuous 24 A operation. IP68 protection remains effective during prolonged immersion up to 3.5 m, resisting moisture, dust and UV degradation without the short-term softening seen in lower-grade plastics. The connector is not designed for permanent submersion beyond the rated depth or for currents above 24 A.

Questions about this item

How can I verify the IP68 junction box is sealing properly after installation?

After tightening all clamping nuts, inspect that both rubber rings sit flush against cables within the Ø5-9 mm or Ø9-12 mm range, then apply power and confirm no moisture ingress during operation.

What comes in the 5-pack and do I need any extra parts?

The pack contains five 3-pole M20 plug connectors with dual-size rubber rings for live, neutral and earth wires; only a screwdriver is required for assembly.

Which cable diameter range should I select for my outdoor lighting project?

Choose the Ø5-9 mm ring for thinner cables or the Ø9-12 mm ring for thicker feeds, matching the actual conductor insulation diameter used in your garden or street-light circuit.
