Terminal connector Pozostali F2.0121 1‑pole in ZU housing for Al/Cu conductors 2.5–50 mm² gray

Single‑pole terminal connector Pozostali F2.0121 in a ZU housing is designed for reliable electrical connections of aluminum and copper conductors with cross‑sections from 2.5 to 50 mm². Supplied in gray, the connector provides a compact, single‑pole solution intended for use in distribution boards, junction boxes and a variety of industrial installations where mixed or like‑metal conductors must be joined securely. The ZU housing offers mechanical protection and simplifies mounting in confined spaces.

Advantages

The single‑pole design enables straightforward connection of individual conductors while maintaining electrical continuity and mechanical stability. Compatibility with both Al and Cu conductors reduces the need for separate terminal types and supports mixed‑metal installations. The wide conductor range (2.5–50 mm²) covers common installation scenarios from small feeders to larger supply conductors. The gray ZU housing gives basic environmental and mechanical protection and helps organize wiring inside panels.

Suitable for

• Distribution boards and consumer units
• Industrial control panels and junction boxes
• Connections between aluminum and copper conductors
• Main feeders, branch circuits and equipment incoming connections

Key specifications

• Poles: single‑pole
• Compatible conductor materials: aluminum and copper
• Conductor cross‑section range: 2.5–50 mm²
• Housing type: ZU (protective insulating housing)
• Color: gray

How to use

Strip the conductor insulation to the length recommended for the terminal type, insert the conductor fully into the connector and tighten the clamping screw or mechanism to the torque value specified by the installation practice for the conductor size and material. Ensure that aluminum conductors are clean and free of oxide before termination and that terminations are checked for secure mechanical and electrical contact. Install the connector inside the distribution board or junction box in a location that allows safe access for inspection and maintenance.

Usage recommendations

Use appropriate torque settings and, for aluminum conductors, follow industry practices such as applying an antioxidant compound where required and performing periodic inspections to prevent loosening. Avoid using the connector beyond its specified conductor range and ensure compliance with local electrical codes when joining Al and Cu conductors.
