Plug ETI ER 3253 — 32 A, 400 V, 3P+N+PE

ETI ER 3253 — 32 A, 400 V, 3P+N+PE is an industrial-grade plug designed for three-phase power distribution with neutral and protective earth. Built to provide reliable electrical connection for heavy-duty equipment and temporary installations, the plug supports continuous current up to 32 A at a nominal voltage of 400 V. The 3P+N+PE configuration ensures correct phase, neutral and earth contact sequencing for safe operation in industrial and construction environments.

Advantages

The plug is constructed for robust mechanical and electrical performance, offering secure mating and stable current carrying ability under load. Its design reduces the risk of accidental disconnection and improves contact reliability in demanding conditions. Materials and contact geometry are selected to meet common industry standards for safety and durability, enabling straightforward installation and maintenance in three-phase systems.

Suitable for

• Powering industrial machinery and motors
• Temporary site power distribution on construction sites
• Connection of distribution boxes and power panels
• Workshops, factories and maintenance facilities

Key specifications

• Rated current: 32 A
• Rated voltage: 400 V (three-phase)
• Contact configuration: 3 phase + neutral + protective earth (3P+N+PE)
• Application type: industrial/temporary power connections
• Mounting style: plug (male connector for mating with compatible sockets)

How to use

Before installation, ensure the supply is isolated and verify that the voltage and current ratings match the intended circuit. Fit cables to the plug according to the manufacturer’s wiring scheme, securing conductors in the correct phase, neutral and earth terminals. Tighten terminal screws to the recommended torque and assemble the housing to protect connections. Connect the plug to a compatible socket only after confirming secure termination and correct polarity.

Usage recommendations

Use the plug in environments for which it is rated, avoid exposure to conditions exceeding its electrical or mechanical limits, and perform periodic inspections of contacts and cable grips. Replace the plug if signs of overheating, corrosion, or mechanical damage are present.
