## Long description

Polam Nakło Portable Plug Fast Connector model 3628-326 is an industrial-grade 16 A, 400 V plug with three phases plus neutral and earth (3P+N+Z). Designed for temporary power distribution, it provides a reliable connection for machinery, workshop equipment, construction sites and events where a durable, standardized connector is required. The housing and contact arrangement conform to common industrial connector form factors and the IP44 ingress protection rating ensures resistance to splashing water and access by solid objects larger than 1 mm, making it suitable for indoor and sheltered outdoor environments.
Advantages
This portable plug offers a compact, robust design that supports safe, quick connections and disconnections in temporary electrical installations. The 16 A current rating and 400 V voltage rating accommodate a wide range of light industrial and professional equipment. Built to industry norms for phase, neutral and earth arrangement, the connector reduces wiring errors and maintains secure mating under normal mechanical stress. IP44 protection contributes to longer service life in workshop and site conditions where exposure to dust and splashing is possible.
Suitable for
Temporary power supply for portable machinery and power tools
Workshop and garage equipment connections
Construction site temporary distribution boards and lighting
Event power distribution for stages, lighting and sound equipment
When it may not be suitable
This connector is intended for temporary and portable installations rather than permanent fixed wiring in harsh outdoor environments. The IP44 rating does not provide protection against heavy water jets or prolonged immersion, so it is not appropriate for locations exposed to heavy rain or submersion. For applications requiring higher current, voltage, or greater ingress protection, a different connector with the appropriate ratings should be selected.
Key specifications
Rated current: 16 A
Rated voltage: 400 V
Contact configuration: 3P + N + Z (three phases, neutral, earth)
Ingress protection: IP44
Application type: portable/temporary industrial connector
How to use
Ensure power is switched off before wiring or connecting the plug. Open the connector housing according to the manufacturer procedure, insert conductors of appropriate cross-section into the designated terminals for phases, neutral and earth, and tighten terminal screws to the specified torque. Reassemble the housing and verify that seals and gaskets are correctly seated to maintain IP44 protection. When connecting to a matching socket, align the plug with the socket keying to ensure correct phase orientation and insert until the coupling engages. After connection, switch power on and verify correct operation of the connected equipment. Regularly inspect contacts, housing and cable entry for wear or damage and replace the connector if corrosion or mechanical damage is present.
What to consider before purchase
Verify compatibility with the mating socket and system phase arrangement
Confirm cable conductor size matches terminal capacity and local wiring regulations
Assess environmental conditions to ensure IP44 is sufficient for the intended location
Check that 16 A and 400 V ratings meet the power requirements of your equipment
Usage recommendations
Use this Polam Nakło portable plug for temporary power distribution in controlled indoor or sheltered outdoor settings. Install with cables and accessories rated for the same current and voltage, perform periodic inspections, and avoid exposure to heavy water jets or immersion to maintain safe operation.
