Why Choose the ILME SQ1665 Switched Socket 16A 415V 5 Pole IP44?
The ILME SQ1665 is a robust interlocked switched industrial socket-outlet designed for three-phase power distribution in factories, workshops, machinery and industrial installations. Rated at 16 A and suitable for 200/346–240/415 V AC supplies, it provides a dependable connection and local switching point for compatible industrial plugs.
The SQ1665 uses a 3P+N+PE five-pole configuration with a 6 h earth contact position and red voltage identification for standard three-phase 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prevents the switch from being turned ON unless a compatible plug is inserted and prevents the plug from being withdrawn while the switch is ON, providing a controlled connection and disconnection sequence.
Designed for flush or panel mounting, the SQ1665 is supplied without a backbox and provides IP44 protection. For wall-mounted installations, the compatible ILME SQC 1114 CS single backbox can be ordered separately. Self-extinguishing thermoplastic construction, a spring-loaded socket cover and a padlockable switch control make the SQ1665 a practical choice for industrial power installations.

Safer Three-Phase Power Connections with Mechanical Interlocking
The ILME SQ series combines an industrial socket-outlet and isolation switch with a mechanical interlocking mechanism. The system prevents the switch from being moved to the ON position when the plug is not inserted and prevents the plug from being withdrawn while the switch is ON. It also prevents removal of the socket from its panel or enclosure while a plug is inserted, supporting safer operation and maintenance.
The 3P+N+PE configuration of the SQ1665 makes it suitable for three-phase installations requiring a neutral conductor as well as protective earth. The socket can be integrated directly into compatible panels and distribution assemblies, while the separately available SQC 1114 CS backbox enables conversion to a fixed wall-mounted arrangement where required.
Typical Applications
- 415 V three-phase industrial machinery.
- Three-phase equipment requiring a neutral connection.
- Factories and manufacturing facilities.
- Industrial workshops and maintenance areas.
- Machine building and OEM electrical systems.
- Industrial control panels and distribution boards.
- Automation equipment requiring locally switched power connections.
