Simet STB 35 SIMBLOCK Screw Terminal Block 35mm2 for Al/Cu Conductors, Grey

The Simet STB 35 SIMBLOCK is a professional-grade screw terminal block engineered for the secure termination of electrical conductors with a cross-section of 35mm2. Designed to accommodate both aluminum and copper wiring, this terminal block provides a reliable and stable connection point within electrical distribution systems. Its robust construction ensures excellent mechanical stability and consistent electrical conductivity, making it a dependable choice for demanding industrial and residential infrastructure projects.

Advantages

The primary benefit of the Simet STB 35 is its versatility in handling different conductor materials, allowing for seamless integration of aluminum and copper wires in the same system. The screw-type mechanism provides a high-pressure contact that minimizes resistance and prevents loosening over time, even under thermal expansion. Its compact design facilitates efficient use of space within electrical enclosures, while the durable grey housing offers protection and clear identification for organized wiring layouts.

Suitable for

• Industrial electrical distribution panels
• Residential power supply installations
• Connecting aluminum and copper power cables
• High-capacity electrical circuit termination

When it may not be suitable

This terminal block is specifically designed for 35mm2 conductors and may not be suitable for wires with significantly smaller or larger cross-sections. It is intended for standard electrical distribution environments and should not be used in applications requiring specialized explosion-proof or high-vibration resistance ratings unless verified for those specific conditions.

Key specifications

• Conductor capacity: 35mm2
• Compatible materials: Aluminum and Copper
• Connection type: Screw terminal
• Color: Grey
• Application: Electrical distribution

How to use

To install the Simet STB 35, ensure the power supply is disconnected. Strip the insulation from the end of the conductor to the appropriate length. Insert the wire into the terminal opening and tighten the screw firmly using a compatible screwdriver to ensure a secure mechanical and electrical connection. Verify that the wire is held tightly and cannot be pulled out before energizing the circuit.

What to consider before purchase

• Ensure the conductor cross-section matches the 35mm2 specification
• Verify compatibility with your existing mounting rail system
• Check that the terminal block meets the current and voltage requirements of your specific installation

Usage recommendations

Always use a calibrated torque screwdriver to ensure the screw is tightened to the manufacturer's recommended torque settings to prevent damage to the conductor or the terminal block.
