Terminal connector (rail) Eti-Polam VS 4 PAN 4 mm² blue, threaded

Eti-Polam VS 4 PAN 4 mm² blue threaded rail terminal connector is a compact DIN-rail mounted terminal for safe and reliable electrical connections in control panels, distribution boards and industrial wiring installations. Designed for conductors up to 4 mm², the product features an insulated blue housing and a screw/threaded clamp that secures conductors mechanically and electrically while keeping a small footprint on standard rails.

Advantages

The threaded clamp provides a robust mechanical connection that resists vibration and maintains consistent contact force. The insulated housing reduces risk of accidental contact and simplifies identification in multi-rail assemblies thanks to the blue color. Its compact rail-mount form factor saves space inside electrical cabinets and allows straightforward grouping of multiple circuits.

Suitable for

• Industrial control panels and automation cabinets
• Electrical distribution boards and junction boxes
• Terminal grouping and signal wiring in machinery
• On-site wiring where secure screw connections are required

Key specifications

• Conductor cross-section: up to 4 mm²
• Mounting: DIN-style rail
• Connection type: screw / threaded clamp
• Housing: insulated, blue color
• Form factor: compact rail-mounted terminal

How to use

Mount the terminal connector onto a compatible DIN-style rail and secure it by applying appropriate mounting force until it clips into place. Strip the conductor to the recommended length, insert the conductor into the terminal entry and tighten the screw/threaded clamp to obtain a firm electrical and mechanical connection. Verify the conductor is held securely and that no bare conductor is exposed outside the insulated housing. For multi-conductor or multi-terminal assemblies, maintain consistent torque values across terminals for even contact pressure.

Usage recommendations

Use a torque screwdriver set to the manufacturer's recommended torque range for screw/clamp tightening. Choose the correct conductor cross-section and insulation stripping length for 4 mm² terminals. Periodically inspect terminal tightness during maintenance, especially in applications subject to vibration or temperature cycling.
