Terminal block Simet SCB 35-2 single-pole Al/Cu 2×35 mm² gray

Terminal block Simet SCB 35-2 single-pole Al/Cu 2×35 mm² gray is designed for branch and distribution connections where reliable transition between aluminum and copper conductors is required. The single-pole screw-clamp terminal accepts two conductors up to 35 mm² each and provides a compact solution for panel wiring, distribution boards and general electrical installations. Constructed to accommodate both Al and Cu conductors, it reduces the need for separate adaptors and helps ensure consistent contact pressure and electrical continuity in mixed-metal systems.

Advantages

The Simet SCB 35-2 offers a secure screw-clamp contact system that maintains stable mechanical and electrical connection for both aluminum and copper conductors. Its single-pole configuration allows straightforward installation and space-efficient arrangement on DIN rails or mounting panels. The gray housing provides clear visual identification while the design minimizes contact resistance and supports reliable current transfer under typical installation conditions.

Suitable for

• Panel wiring and distribution boards in residential and industrial installations
• Branching and distribution of power where Al and Cu conductors are used together
• Electrical cabinets and terminal blocks assemblies requiring compact single-pole termination
• Situations requiring two conductors per pole with cross-sections up to 35 mm²

When it may not be suitable

This terminal block is not intended for use beyond its rated conductor sizes or for applications requiring more complex multi-pole switching or integrated protection. For high-vibration environments, specialized vibration-resistant or spring-clamp terminals may be preferable. Do not use it where manufacturer or local regulations prohibit mixed-metal connections without additional corrosion protection.

Key specifications

• Conductor accommodation: two conductors per pole, up to 35 mm² each
• Compatible conductor materials: aluminum (Al) and copper (Cu)
• Connection type: screw-clamp
• Poles: single-pole
• Housing colour: gray
• Intended mounting: panel/terminal rail assemblies

How to use

Strip the insulation from the conductors to the recommended length, insert each conductor into the respective entry point and tighten the screw-clamp to the torque specified by installation standards or local regulations. Ensure aluminum conductors are properly cleaned and, if required by local practice, treated with an anti-oxidation compound before termination. After tightening, verify mechanical stability and electrical continuity with appropriate test equipment. Follow standard safety procedures and switch off power before performing any wiring work.

What to consider before purchase

• Verify conductor cross-sections do not exceed 35 mm² for each connected wire
• Confirm compatibility with mixed Al/Cu installations and applicable installation codes
• Assess mounting space and whether a single-pole terminal meets the system layout requirements
• Check required torque values and any need for anti-oxidation treatment for aluminum conductors

Usage recommendations

Use appropriate tools to achieve correct screw torque, treat aluminum conductors when required, and perform a continuity and tightness check after installation. For installations subject to vibration or specific certification requirements, consult product documentation or select terminals designed for those conditions.
