The IEC 309-2 Industrial Plug Series offers a dependable single-phase power connection solution engineered to meet the rigorous demands of industrial and commercial installations. Available in 16A and 32A current ratings, each plug features a 3P+E pole configuration with a 6h earth contact position, fully compliant with IEC 60309-1 and IEC 309-2 international standards.
Constructed from flame-retardant engineering thermoplastic and fitted with high-conductivity brass contacts, these plugs are designed for long service life under continuous mechanical and electrical stress. The secure cable grip structure simplifies field installation while maintaining robust strain relief.
Targeted at electrical contractors, plant engineers, and facility managers, this plug series is the preferred choice for industrial machinery connections, temporary power distribution, construction sites, and factory floor applications where safety and reliability are non-negotiable.
The IEC 309-2 Industrial Plug Series is purpose-built for single-phase power distribution in environments where standard domestic connectors are inadequate. The 3P+E, 6h configuration provides a keyed, polarised interface that prevents accidental mismatching of voltage levels, a critical safety feature on multi-voltage industrial sites. Both the 16A and 32A variants share the same fundamental design philosophy: robust construction, minimal contact resistance, and straightforward field wiring.
The housing is moulded from engineering-grade thermoplastic selected for its flame-retardant properties, high dielectric strength, and resistance to oils, solvents, and UV exposure commonly encountered in industrial settings. Brass contacts are precision-machined to ensure consistent mating force and low contact resistance throughout the product's service life. The integrated cable grip accommodates a range of cable outer diameters, reducing installation time and ensuring compliance with strain-relief requirements.
With an IP44 protection rating, these plugs are equally suited to permanent indoor panel connections and temporary outdoor power distribution, making them a versatile, cost-effective solution for electrical infrastructure across manufacturing, construction, and utilities sectors.
Each plug in this series employs a screw-terminal wiring system that accepts standard industrial cable conductors, enabling secure, low-resistance terminations without specialist tooling. The brass contact pins are dimensioned and positioned in accordance with IEC 309-2 to guarantee correct engagement depth and contact pressure with compliant socket-outlets. The thermoplastic body is moulded as a two-part clamshell assembly, with the cable entry gland and grip integrated into the rear housing to provide simultaneous IP44 sealing and mechanical strain relief.
Electrical insulation between live, neutral, and earth conductors is maintained by high-dielectric-strength thermoplastic barriers, achieving an insulation resistance of ≥ 10 MΩ under standard test conditions. The contact geometry and housing design collectively ensure that the plug can be repeatedly inserted and withdrawn under load conditions without degradation of contact integrity or IP rating performance.
