## Summary description

Eti-Polam VS 4 is a screw-type terminal connector designed for DIN-rail mounting, suitable for conductors up to 4 mm². Finished in beige, it provides a secure threaded connection for electrical installations, distribution blocks, and control panels. Use for reliable conductor termination, branch connections, and wiring in residential and industrial panels.

## Long description

Eti-Polam VS 4 is a screw-type terminal connector designed for mounting on standard DIN rails. Finished in beige, this compact terminal accepts conductors up to 4 mm² and provides a threaded clamping point for secure electrical connections in distribution boards, control panels and industrial or residential installation cabinets. The product is intended to deliver stable, low-maintenance terminations for multi‑wire and single‑wire conductors where a durable mechanical and electrical connection is required.
Advantages
The terminal connector offers a screw clamping mechanism that ensures firm contact and straightforward installation or removal of conductors. Its DIN-rail compatibility allows quick integration into existing distribution systems and simplifies panel wiring. The neutral beige housing provides visual consistency in panel assemblies while offering electrical insulation and mechanical protection for the connection point.
Suitable for
 Termination and branching of copper conductors up to 4 mm² in distribution and control panels
 DIN-rail mounted wiring in residential and light industrial electrical cabinets
 Repair or extension of existing terminal blocks and distribution strips
 Applications that require a screw-type, reusable terminal with a compact footprint
When it may not be suitable
This terminal connector is not intended for conductors larger than 4 mm² or for applications that require crimp-only or spring-clamp terminations. It may also be unsuitable where protection ratings, high vibration resistance, or specific approvals (e.g., hazardous area certifications) are required unless those conditions are verified against installation standards.
Key specifications
 Mounting type: DIN-rail
 Connection type: screw clamping
 Maximum conductor cross-section: 4 mm²
 Housing color: beige
 Typical use: distribution boards, control panels, terminal strips
How to use
Mount the terminal connector onto a compatible DIN rail by engaging the housing clip and pressing until it clicks into place. Strip the conductor insulation according to accepted electrical installation practice, insert the conductor into the terminal entry, and tighten the screw clamp to the recommended torque for the conductor size to ensure secure contact. For multi‑wire conductors with ferrules, insert the ferruled end and tighten the screw. To remove a conductor or the terminal from the rail, loosen the screw and release the housing clip following safe isolation procedures.
What to consider before purchase
 Confirm the conductor cross-section does not exceed 4 mm² for proper clamping
 Ensure the DIN-rail size and panel space are compatible with the terminal's dimensions
 Check whether a screw-type terminal meets the installation's vibration, environmental and safety requirements
 Decide if ferrules or insulated connectors are required for the conductor type used
Usage recommendations
Follow local wiring regulations and recommended torque values when tightening screws. Use appropriate ferrules on stranded conductors for improved contact reliability. Verify the terminal is seated correctly on the DIN rail and routinely inspect connections for tightness in critical installations.
