Terminal connector Simet 84703003 AL/CU ZGG2x35/2x35n blue – threaded rail connector for 35 mm² aluminium/copper

Simet 84703003 AL/CU ZGG2x35/2x35n blue is a threaded rail terminal connector designed for secure mechanical and electrical joining of aluminium and copper conductors up to 35 mm² on standard mounting rails. The compact connector is intended for DIN-rail environments and provides a stable interface for mixed-metal conductor connections where space is limited and reliable contact is required in distribution boards, industrial panels and electrical installations.

Advantages

This connector allows direct coupling of aluminium and copper conductors in a single terminal, reducing the need for separate adapters or transition sleeves. The threaded design ensures consistent clamp force and dependable conductivity, while the compact blue housing facilitates neat DIN-rail installation and easy identification. Materials and construction are selected to minimise galvanic issues and to provide mechanical stability under typical electrical panel conditions.

Suitable for

• Distribution boards and subpanels where aluminium and copper conductors meet
• Industrial control panels and electrical cabinets with DIN-rail mounts
• Retrofit or upgrade projects converting conductor types or adding new circuits
• Applications requiring compact, mixed-metal terminal connections up to 35 mm²

Key specifications

• Conductor compatibility: aluminium and copper
• Maximum conductor cross-section: up to 35 mm²
• Mounting type: DIN-rail / threaded rail connector
• Connection style: threaded/clamp terminal for secure mechanical joint
• Housing colour: blue (visual identification on rail)
• Form factor: compact for space-efficient rail installations

How to use

Mount the connector on the appropriate DIN rail and prepare conductors by stripping insulation to the required length for a clean, solid contact. Insert aluminium or copper conductors into the designated entry points and tighten the threaded clamps to the torque recommended by the installer’s practice or applicable standards. Verify mechanical tightness and electrical continuity after installation and ensure that conductor ends are properly positioned to avoid strand splaying or loose contact.

Usage recommendations

Use a calibrated torque driver or follow local electrical installation standards to tighten the threaded terminals. Where applicable, apply approved anti-oxidation treatment on aluminium conductors before connection and perform periodic inspections to check for loosening or corrosion in mixed-metal joints.
