TM1644SIR Ilme Switched socket 16amp 110v 4p IP67 room for RCD w/o box

Why Choose the Ilme TM1644SIR Interlocked Switched Socket?

The Ilme TM1644SIR is a robust 16 A industrial interlocked switched socket outlet designed for low-voltage power distribution and applications requiring space for additional modular protection or control equipment. Part of the Ilme TM series, it is rated for 100-130 V AC at 50 / 60 Hz and uses yellow identification for this voltage range.

The TM1644SIR features a 3P + PE (4-pin) configuration with the protective earth contact at the 4 h position. Its mechanical interlock prevents the switch from being turned on unless a compatible plug is inserted and prevents removal of the plug while the switch is on, providing controlled connection and disconnection of industrial electrical equipment.

A key feature is the integrated compartment for modular equipment, providing 4.5 DIN-rail modules on an EN 60715 TH 35-7.5 rail. This allows suitable modular equipment, such as an appropriately selected RCD or other protective device, to be incorporated into the installation. The TM1644SIR is supplied without a back box and provides IP66 / IP67 protection when correctly installed with compatible components.

Key Advantages

• 16 A, 100-130 V AC industrial interlocked switched socket outlet.
• 3P + PE (4-pin) configuration with 4 h earth position.

Interlocked Power Connection with Space for Modular Protection

Industrial interlocked switched socket outlets combine a socket outlet and switch with a mechanical safety sequence. On the TM1644SIR, the switch cannot be turned on until a compatible plug has been inserted, while the plug cannot be withdrawn while the switch remains on. The modular compartment adds another level of installation flexibility by providing space for suitable DIN-rail-mounted electrical equipment.

The compartment accommodates 4.5 modules on an EN 60715 DIN rail and has an inspection panel that can only be opened when the main switch is off. This arrangement makes the TM1644SIR particularly useful where an RCD, circuit protection or other compatible modular device needs to be incorporated close to the industrial socket outlet.

Typical Applications

• 110 V industrial power distribution systems.
• Industrial socket installations requiring provision for an RCD.
• Factory and production machinery.
• Construction and site electrical distribution.
• Workshops and maintenance facilities.
• Industrial control and power distribution panels.
• Portable and fixed equipment requiring mechanically interlocked power connections.
