Industrial Plugs & Sockets

Lewden industrial plugs and sockets comply with BS EN 60309-1 and IEC 60309-2 standards, ensuring robust construction for industrial applications, including proper pin coding to prevent incorrect mating and verification of IP protection levels. This makes them suitable for site installations requiring certified equipment and meets UK and EU safety regulations for reliable performance in demanding environments.

The Lewden range supports common industrial voltages such as 110V, 240V and 415V AC, with current ratings including 16A, 32A and 63A. For example, a 16A 2P+E 110V plug is ideal for low-voltage tools on construction sites, while 32A options handle heavier loads for higher power equipment and machinery.

IP44 provides basic protection against solid objects >1mm and water splashes, suitable for sheltered outdoor or indoor industrial use. For harsher environments, opt for IP66/IP67 models, which offer dust-tight sealing and protection against powerful water jets or temporary immersion—essential for wet trades, marine, or high-pressure washdown areas. Choose based on your site's exposure to ensure long-term durability and safety.

Lewden provides 2P+E for single-phase 110V/240V applications (e.g., portable tools), 3P+E for three-phase balanced loads without neutral (common in motors and lighting), and 3P+N+E (often listed as 4P+E) for three-phase with neutral (e.g., unbalanced loads or 415V systems). Select based on your load balance and phase requirements to ensure compliance and prevent overloads.

Yes, Lewden plugs are fully interchangeable with other IEC 60309-compliant makes due to standardised pin configuration and color coding (e.g., blue for 230V). Always verify cable gland compatibility and ensure matching IP ratings to maintain enclosure integrity on mixed-brand setups.

Constructed from high-impact thermoplastic, Lewden plugs withstand temperatures from -25°C to +50°C, resist most industrial chemicals (oils, solvents), and feature ergonomic designs for gloved use. They're engineered for vibration-heavy environments like generators or machinery, reducing downtime for contractors.

Lewden RCD sockets incorporate 30mA residual current devices for earth leakage protection, tripping in < 40ms to mitigate shock hazards in damp or high-risk areas. Ideal for BS 7671-compliant installs on construction sites—pair with interlocked switches to prevent live insertion/removal. This built-in safety feature helps prevent electrical accidents and complies with UK wiring regulations.

Angled sockets optimise cable routing in tight spaces, reducing strain relief needs. Switched interlocked models mechanically prevent plug insertion/removal under load, complying with isolation requirements and minimising arc flash risks. These features improve efficiency and safety in confined industrial or construction areas.

Lewden splitters distribute power from a single feed with maintained IP44 sealing for flexible power distribution. Common 3-way models, like the 16A 230V versions, allow secure cable tie mounting for quick temporary setups on sites, ensuring reliable multi-device power without compromising protection.

Lewden products typically come with a 2-year warranty against manufacturing defects. For maintenance, regularly inspect for damage, clean with a damp cloth (avoid harsh chemicals), and check connections for tightness.
