This guide is an engineering and procurement aid. The final enclosure, junction-box, protection, and installation decisions must follow the equipment data, local requirements, approved drawings, and the supplier’s documented capability. A search result or competitor page is not evidence that ElectricalCabinet.net offers a particular rating or certification.
Different exposures require different questions
IP68 and IP69 address different environmental scenarios. An installation may involve immersion, high-pressure cleaning, elevated temperature, chemicals, or several of these at different times. Select the enclosure and accessories from the real sequence of exposure rather than treating the highest-looking number as a complete design.
Build the exposure profile
| 項目 | Record before selection |
|---|---|
| Cleaning method | Pressure, distance, temperature, chemicals, frequency, and direction. |
| Immersion condition | Depth, time, medium, temperature, and whether the cabinet is energized. |
| Materials and seals | Compatibility of body, gasket, fasteners, windows, and cable entries. |
| Maintenance cycle | How often doors, glands, and covers are opened, replaced, or re-torqued. |
Complete-assembly evidence
Check the body, door interface, hinges, locks, glands, plugs, vents, and mounting orientation. A cooling or pressure-equalization accessory may change the evidence. Ask the supplier to identify the tested configuration and the limits of the result, then record any site-specific installation controls.
Use these inputs to prepare an evidence-based electrical enclosure enquiry and confirm the final configuration with the responsible engineer and supplier.
