Terminal connector Simet AL-CU 1.5–50 mm² threaded for busbar TS 35, earthing yellow-green, 1 pc

Simet AL-CU terminal connector designed for safe transitions between aluminium and copper conductors and for connection to a TS 35 DIN busbar. The connector accepts conductor cross-sections from 1.5 to 50 mm² and features a threaded fastening compatible with standard busbar mounting. The yellow-green colour identifies the component for protective earth/grounding use. The product is supplied as a single piece for installation in distribution boards and electrical panels where earthing continuity and conductor compatibility are required.

Advantages

The terminal connector supports both aluminium and copper conductors within the specified cross-section range, reducing the need for separate connectors and simplifying inventory. Threaded fastening ensures a secure mechanical and electrical connection to the TS 35 busbar. The yellow‑green insulation or marking provides visual identification for protective earth, facilitating correct wiring and maintenance. The design is compact for space-efficient mounting in electrical panels.

Suitable for

• Earthing/grounding connections in distribution boards and switchgear
• Transition joints between aluminium and copper conductors
• DIN rail/TS 35 busbar installations in residential, commercial and light industrial panels
• Retrofit or new installations where a single versatile connector for AL and CU is needed

Key specifications

• Conductor cross-section range: 1.5–50 mm²
• Compatible conductor materials: aluminium (AL) and copper (CU)
• Mounting type: threaded fastening for TS 35 DIN busbar
• Application: protective earth/grounding connection
• Quantity: single piece
• Visual identification: yellow-green for protective earth

How to use

Ensure power is isolated before working on the panel. Prepare conductor ends by stripping insulation to the recommended length and, if required by local practice, fit appropriate ferrules or anti-oxidation treatment for aluminium conductors. Position the connector on the TS 35 busbar and secure using the threaded fastening until a firm mechanical and electrical contact is achieved. Insert the prepared conductor into the connector and tighten to the torque recommended by relevant electrical standards or local regulations. Verify continuity and tightness after installation.

Usage recommendations

Use suitable anti-oxidation compound or approved aluminium-to-copper treatment when connecting dissimilar metals; follow local electrical codes for torque settings and verification. Regularly inspect earthing connections for tightness and corrosion during maintenance intervals.
