Why Choose the ILME SQ1664C Switched Socket 16A 415V 4 Pole IP44?
The ILME SQ1664C is a robust wall-mounted interlocked switched industrial socket-outlet designed for three-phase power distribution in factories, workshops, machinery and industrial installations. Rated at 16 A and designed for 380–415 V AC supplies, it provides a dependable connection and local isolation point for compatible industrial plugs.
The SQ1664C uses a 3P+PE four-pole configuration with a 6 h earth contact position and red voltage identification for 380–415 V industrial supplies. Its integrated mechanical interlock prevents the switch from being turned ON unless a compatible plug is inserted and prevents the plug from being withdrawn while the switch is ON, providing a controlled connection and disconnection sequence.
Supplied in a wall-mounted configuration, the SQ1664C combines the ILME SQ switched socket with the appropriate enclosure for convenient surface installation. Its IP44 protection rating, self-extinguishing thermoplastic construction, spring-loaded socket cover and lockable switch make it a practical solution for demanding indoor and sheltered industrial environments.

Safer Three-Phase Power Connections with Mechanical Interlocking
The ILME SQ system combines an industrial socket-outlet and isolation switch with a mechanical interlocking mechanism. The interlock prevents the switch from being moved to the ON position unless a compatible plug has been inserted and prevents the plug from being removed while the switch remains ON. This controlled operating sequence helps reduce the possibility of connecting or disconnecting equipment under load.
For three-phase machinery, the SQ1664C provides a convenient local connection and switching point with a 3P+PE configuration. Its wall-mounted enclosure makes it suitable for fixed installations where a readily accessible 415 V equipment supply is required, while the IP44 construction provides protection against solid objects greater than 1 mm and splashing water when correctly installed.
Typical Applications
- 415 V three-phase industrial machinery.
- Factories and manufacturing facilities.
- Industrial workshops and maintenance areas.
- Pumps, motors and processing equipment.
- Machine building and OEM electrical systems.
- Industrial power distribution installations.
- Automation equipment requiring local switched power connections.
