TM1665SSPX Ilme Atex switched socket 16a 415v 5p IP67 without backbox

Why Choose the Ilme TM1665SSPX ATEX Interlocked Switched Socket?

The Ilme TM1665SSPX is a robust 16 A ATEX interlocked switched socket outlet designed for three-phase industrial power distribution in areas where combustible dust may be present. Part of the specialised Ilme TM-Ex range, it combines industrial socket connectivity, mechanical interlocking and ATEX-compliant construction for demanding hazardous-area installations.

The TM1665SSPX features a 3P + N + PE (5-pole) configuration with the protective earth contact at the 6 h position. Its rated voltage range is 200/346-240/415 V AC at 50 / 60 Hz, making it suitable for nominal 400 V and 415 V three-phase systems requiring neutral. Red identification corresponds to this IEC industrial socket voltage configuration.

Supplied without a fuse carrier and without a base box, the TM1665SSPX is designed for installation with a suitable Ilme TM-Ex single or multiple enclosure. It provides IP66 / IP67 protection, IK10 impact resistance and an II 3D, Ex tc IIIC T65 °C Dc classification for suitable combustible-dust applications when correctly installed.

Key Advantages

• Purpose-designed ATEX interlocked switched socket for combustible-dust environments.
• 16 A, 200/346-240/415 V AC rating for three-phase systems with neutral.
• 3P + N + PE (5-pole) configuration with 6 h earth position.
• Mechanical interlock prevents switching on without a compatible plug inserted.
• Compatible plug cannot be removed while the switch remains in the ON position.
• IP66 / IP67 protection for demanding industrial environments.
• IK10 / 20 J impact resistance provides robust mechanical protection.

ATEX Interlocked Three-Phase Power with Neutral

Industrial interlocked switched socket outlets combine a power socket with a mechanically linked switch so that connection and isolation follow a controlled sequence. On the TM1665SSPX, the switch cannot be turned on unless a compatible plug is inserted, while the plug cannot be removed with the switch in the ON position. This arrangement helps prevent connection or disconnection while the socket contacts are energised.

The 3P + N + PE arrangement provides three phases, neutral and protective earth, making the TM1665SSPX suitable for equipment requiring a five-pole three-phase supply. Its II 3D, Ex tc IIIC T65 °C Dc marking and IP66 / IP67 construction support appropriately designed installations in industrial locations where combustible dust may be present.

Typical Applications

• ATEX Zone 22 industrial power distribution installations.
• Three-phase machinery requiring neutral and protective earth.
• Facilities where combustible dust may be present.
• Food, grain and ingredient processing equipment.
• Powder handling and production machinery.
• Industrial packaging and material handling systems.
• 400 / 415 V industrial equipment requiring interlocked five-pole connections.
