Mining and heavy industry: dust, water and high current
Mines, processing plants and heavy fabrication share the same conditions: heavy dust, frequent wash-down, high-current equipment and rough handling. How to fix the IP rating, why a mechanical interlock is mandatory, and what to watch on high-current terminals.
Mines, processing plants and heavy fabrication share the same conditions: dust, water, heavy equipment and frequent maintenance. An electrical connection here is not about "being adequate" — it has to survive rough handling.
Three hard requirements
- IP67 minimum: dust plus wash-down or spray — IP44 will not hold up.
- A mechanical interlock is mandatory: live plugging is practically routine on site, and the interlock is the last line of defence.
- High current wired properly: cable size, terminal crimp and torque — compromise any one and it heats.
What we recommend
| Use | Models |
|---|---|
| Interlocked maintenance socket | 5112A (63A 230V 5-pole IP67 DUO) |
| High current (200–400A) | 75091 (250A) · 75116 (400A wall-mounted socket) · 75096 (400A plug) |
| Multi-circuit distribution | 920005, 920015 (socket combinations) |
