SQ1644 Ilme Switched socket 16 amp 110v 4 pole IP44 (without backbox)

Why Choose the Ilme SQ1644 Interlocked Switched Socket?

The Ilme SQ1644 is a robust interlocked switched industrial socket-outlet designed for controlled connection and isolation of electrical equipment in industrial power distribution systems. Rated at 16 A for the 100–130 V AC voltage range, including nominal 110 V applications, it features a 4-pole, 3P+E configuration and IP44 protection.

Part of the Ilme SQ series, the SQ1644 combines an industrial socket with a lockable command switch and mechanical interlocking. The interlock is designed to prevent the switch from being turned to the ON position unless the plug is inserted and to prevent withdrawal of the plug while the switch is ON, helping provide controlled operation in machinery, workshops and industrial distribution systems.

The SQ1644 is supplied without a back box and is intended for installation in compatible Ilme single or multiple enclosure systems. Its socket has a 4h earth-contact position and yellow voltage identification for the 100–130 V AC range, while the insulating self-extinguishing thermoplastic construction provides a durable solution for demanding industrial environments.

Controlled Industrial Power Connection and Isolation

Interlocked switched socket-outlets combine the connection point and switching function in a mechanically coordinated assembly. On the Ilme SQ system, the interlock prevents the switch from being turned ON when a compatible plug is not inserted and prevents the plug from being withdrawn while the switch remains ON, reducing the possibility of routine disconnection while the circuit is energised.

The SQ1644 combines this interlocking arrangement with a 16 A, 3P+E industrial socket for the 100–130 V AC range. Supplied without a back box, it can be integrated into compatible Ilme FC, FM, QM, QP and QG enclosures or an appropriate single box to create a complete industrial power distribution installation.

Typical Applications

• Industrial machinery and production equipment.
• 110 V industrial power distribution.
• Workshop and manufacturing installations.
• Machine and equipment power connection points.
• Industrial distribution boards and enclosure systems.
• OEM machinery and automated production equipment.
