Why Choose the ILME SQE1664 Interlocked Switched Socket?
The ILME SQE1664 is a robust 16 A 380–415 V AC industrial interlocked switched socket designed for safe and reliable three-phase power distribution in machinery, manufacturing and industrial installations. Part of the ILME SQE interlocked switched socket series, it combines an industrial socket outlet with a mechanically interlocked switch to provide controlled connection and isolation of electrical equipment.
The mechanical safety interlock prevents the switch from being turned on without a compatible plug inserted and prevents the plug from being removed while the switch is in the ON position. The switch operating knob is lockable for secure isolation, while the socket is manufactured from self-extinguishing insulating thermoplastic for dependable service in demanding industrial environments.
With a rated current of 16 A, an operating voltage range of 380–415 V AC at 50 / 60 Hz and a 3P+E four-pole configuration, the SQE1664 is suitable for three-phase industrial equipment and machinery. The red voltage-coded socket uses the standard 6h earth contact position and provides IP44 protection. This version is supplied without a backbox for panel mounting or installation with a compatible ILME enclosure.

Safe Three-Phase Industrial Power Connection and Isolation
Interlocked switched sockets such as the ILME SQE1664 combine an industrial socket outlet and local switching within a mechanically linked assembly. The interlock prevents the switch from being closed when the plug is absent and prevents the plug from being withdrawn while the switch is closed, helping reduce the risk of electrical arcing and accidental disconnection under load.
The SQE series is designed for industrial power distribution applications where reliable connections and controlled isolation are essential. Its 3P+E configuration makes the SQE1664 suitable for three-phase equipment that does not require a neutral connection, while its panel-mounting format allows integration into machinery, distribution panels and compatible industrial enclosures.
Typical Applications
- 400 V and 415 V three-phase industrial power distribution.
- Industrial machinery and production equipment.
- Motors, pumps and processing equipment.
- Factory and manufacturing electrical systems.
- Industrial workshops and maintenance facilities.
- Packaging and material handling machinery.
- Electrical distribution panels and enclosure systems.
- OEM machinery and industrial installations.
