## Summary description

Eti-Polam VS 4 PA+ is a red threaded rail terminal connector for 4 mm² conductors. Designed for secure electrical connections on distribution rails, it provides a reliable screw-clamp contact for single or stranded wires. Suitable for industrial and residential electrical panels, junctions and control cabinets where compact, color-coded terminations are required.

## Long description

Eti-Polam VS 4 PA+ red is a threaded rail terminal connector designed for secure screw-clamp connections of single or stranded conductors up to 4 mm². The compact, color-coded red housing is built for mounting on distribution rails and provides consistent electrical contact in residential and industrial panels, junctions and control cabinets where clear phase or circuit identification is required.
Advantages
The connector offers a threaded screw-clamp contact that ensures reliable mechanical and electrical connection for 4 mm² conductors. Its compact profile allows efficient use of rail space while the red color simplifies identification and wiring organization. The product is compatible with standard DIN-style distribution rails and is manufactured to provide stable contact pressure over repeated insertions and removals.
Suitable for
 Connecting single-core or stranded copper conductors up to 4 mm² on DIN rail systems
 Color-coded phase or circuit identification in distribution boards and control cabinets
 Wiring tasks in residential, commercial and light industrial electrical installations
 Terminal assemblies and junction blocks where compact threaded connections are required
When it may not be suitable
This terminal connector is designed for conductors with cross-sections up to 4 mm²; it is not suitable for larger gauge cables or busbars that require higher current capacity. It is intended for standard screw-clamp terminations on distribution rails and may not be appropriate for insulation-displacement systems, specialized high-vibration environments without additional securing measures, or for applications requiring integrated fusing or surge protection.
Key specifications
 Conductor capacity: up to 4 mm² (single or stranded conductors)
 Connection type: threaded screw-clamp contact
 Mounting: rail-mounted for standard distribution rails
 Housing color: red for circuit or phase identification
 Form factor: compact terminal for space-efficient rail installation
How to use
Mount the connector on the distribution rail until it locks into position. Strip the conductor to the recommended length for secure contact, insert the conductor into the terminal entry and tighten the screw to the appropriate torque specified for screw-clamp terminals. Verify the mechanical tightness and electrical continuity after installation and, if required, label the terminal according to circuit identification standards. For repeated maintenance, loosen the screw fully before removing the conductor to avoid conductor damage.
What to consider before purchase
 Confirm conductor cross-section does not exceed 4 mm² and that wire type (solid or stranded) is compatible
 Ensure the distribution rail type and dimensions are compatible with the terminal mounting method
 Check required tightening torque and whether insulating sleeves or markers are needed for your installation
Usage recommendations
Use a properly calibrated screwdriver and follow recommended torque values for screw-clamp terminals to ensure reliable contact. For installations subject to vibration, consider additional securing methods or periodic retorque checks. Maintain clear labeling and color-coding on the rail to simplify future maintenance and reduce wiring errors.
