ORNO industrial power plug 16A 4P IP44 model IVN 1643

The ORNO industrial power plug 16A 4P IP44 model IVN 1643 is a durable mains connector designed for demanding environments. With a 4-pole configuration and IP44 protection, this plug supports safe connections where protection against splashing water and solid objects is required. It is suitable for both single-phase and three-phase wiring setups that use four conductors and is intended for industrial, workshop, construction site and outdoor temporary power applications.

Advantages

This ORNO 16A industrial plug offers mechanical robustness and stable electrical contact under frequent use. The IP44-rated housing provides protection against splashing water and ingress of solid objects greater than 1 mm, improving safety in damp or dusty conditions. Ergonomic design allows reliable cable clamping and strain relief, while the four-pole configuration enables flexible wiring options for various equipment types. The plug is built for repeated connection cycles and provides predictable performance in typical industrial and outdoor scenarios.

Suitable for

• Temporary power feeds on construction sites
• Workshop and garage machinery connections
• Outdoor events and temporary installations with weather exposure
• Industrial equipment requiring 4-pole wiring (single-phase with earth or three-phase systems)

Key specifications

• Rated current: 16 A
• Number of poles: 4
• Degree of protection: IP44 (protection against solid objects >1 mm and splashing water)
• Application: industrial and outdoor temporary power connections
• Construction: robust housing with cable strain relief and secure contact terminals

How to use

Ensure power is switched off before installation. Strip the cable to the manufacturer-recommended lengths, open the housing, and insert conductors into the corresponding terminals following standard wiring conventions for the intended system (single-phase with earth or three-phase). Tighten the terminal screws to achieve secure contact and engage the cable clamp for proper strain relief. Close and secure the housing, then verify continuity and insulation before switching the supply on. Regularly inspect the plug for damage, dirt or moisture ingress and replace if mechanical or electrical defects are found.

Usage recommendations

Use the plug only within its rated current and environmental protection limits. For outdoor or wet conditions, ensure mating sockets and connected equipment provide compatible IP protection. Periodic visual inspection and testing are recommended to maintain safe operation.
