Terminal block Pozostali F2.0308 in ZU housing, 5‑pole (5×50 mm²) 3L+N+PE Al/Cu

Pozostali F2.0308 in ZU housing is a 5‑pole terminal block designed for use with conductors up to 50 mm². Configured as 3L+N+PE, this terminal block accepts both aluminium and copper conductors and provides screw clamping to ensure secure connections. Assembled in a ZU plastic housing, it is intended for electrical panels, junctions and industrial wiring installations where organized distribution of three phases, neutral and protective earth is required.

Advantages

The terminal block supports mixed Al/Cu conductor use and screw clamping for reliable electrical contact and mechanical stability. Its five‑pole layout (three phases, neutral and protective earth) enables compact, organized wiring within switchgear and distribution panels. The ZU housing provides insulation and mounting convenience while helping to maintain separation between poles and reduce installation errors.

Suitable for

• Distribution and control panels in residential, commercial and industrial installations
• Terminal junctions where three phases, neutral and protective earth must be distributed
• Cabinet wiring and DIN‑rail mounted assemblies requiring compact multi‑pole termination
• Applications using aluminium or copper conductors up to 50 mm² cross‑section

Key specifications

• Configuration: 5 poles arranged as 3L + N + PE
• Conductor capacity: up to 50 mm² per pole
• Compatible conductor materials: aluminium (Al) and copper (Cu)
• Connection method: screw clamping
• Housing type: ZU insulated enclosure
• Intended use: panel and junction wiring for three‑phase systems with protective earth

How to use

Mount the terminal block in the ZU housing according to panel layout and secure the housing to the mounting surface or DIN rail as applicable. Prepare conductors by stripping the insulation to the recommended length for the screw terminals. Insert each conductor into its designated pole (L1, L2, L3, N, PE) and tighten the screw clamps to the manufacturer's recommended torque to ensure reliable contact without damaging the conductor, taking care to follow guidelines for Al and Cu conductors. Verify that all connections are secure and that protective earth is correctly bonded before energizing the circuit.

Usage recommendations

Use properly rated ferrules or liners for stranded conductors, and apply the correct torque for aluminium and copper conductors to avoid loosening or over‑stress. Maintain clear labeling of poles in the panel and inspect connections periodically, especially in environments subject to vibration or thermal cycling.
