MENNEKES CEE – DUOi with LED voltage indicator
The new switch-disconnector interlocked wall socket-outlet in 16 and 32 A
DUOi: always in control of the operating status
MENNEKES' new switch-disconnector interlocked DUOi wall socket-outlet gives you an immediate view of the operating status. The integrated LED voltage indicator shows the status of the unit in a power network of up to 3 phases: green means switched on and operational. No LED indicates that the unit is switched off or that a fault may be present. This allows faults to be identified and resolved quickly.
DUOi: smart control for your workflow
For industrial environments such as production sites, ports and shipyards, DUOi guarantees a safe, reliable and efficient power supply. Available in 16 and 32 A, with 3, 4 and 5 poles.
Why choose DUOi?
Faster installation
- 180° rotatable base for cable entry from above or below. Four breakout cable entries with pre-formed M25 and M32 threads eliminate the need for blanking plugs.
- Removable mounting plate for fast and easy connection. The socket-outlet and switch-disconnector are pre-wired and fitted to the mounting plate.
- Four smart, captive combi-head screws with dual thread, made of plastic.
Safe and easy operation
- Switch-disconnector with rotary handle: in the OFF position the plug can be inserted or removed; in the ON position the plug is mechanically interlocked and cannot be removed under load.
- Hinged lid with rubber grips and IP67 rating for safe use, even in damp conditions. The upward-opening lid prevents interference with cables and cable glands.
- An optional lockout-tagout facility prevents unwanted re-energising, even with the plug inserted.
- X-CONTACT® reduces the force required to plug and unplug by 50%.
DUOi: smart control, safe operation and time savings on every installation.
