Simet STB 35 SIMBLOCK Rail Terminal Block 35mm2 for Al/Cu Conductors

The Simet STB 35 SIMBLOCK is a professional-grade screw-type rail terminal block engineered for the secure termination of 35mm2 conductors. Designed to accommodate both aluminum and copper wires, this component ensures a stable and low-resistance electrical connection within industrial control panels and residential distribution boards. Its robust construction facilitates reliable performance in demanding electrical environments, providing a dependable solution for power distribution needs.

Advantages

The primary advantage of the Simet STB 35 lies in its versatility, as it is specifically certified for use with both aluminum and copper conductors, which is essential for modern electrical installations. The screw-type clamping mechanism ensures a high-pressure contact that maintains integrity over time, reducing the risk of overheating or connection failure. Furthermore, the compact design allows for efficient space utilization on standard DIN rails, simplifying the assembly process in crowded electrical enclosures.

Suitable for

• Industrial electrical distribution systems
• Residential power distribution boards
• Connecting aluminum and copper power cables
• DIN rail mounted electrical installations

When it may not be suitable

This terminal block is not intended for use with conductors outside the specified 35mm2 cross-section range. It is also not suitable for applications requiring specialized environmental protection, such as direct exposure to moisture or corrosive chemicals without an appropriate protective enclosure.

Key specifications

• Conductor cross-section: 35mm2
• Compatible conductor materials: Aluminum (Al) and Copper (Cu)
• Mounting type: DIN rail
• Connection method: Screw-type

How to use

To install the Simet STB 35, first ensure the power supply is disconnected. Secure the terminal block onto the standard DIN rail until it clicks into place. Strip the insulation from the end of the conductor to the appropriate length. Insert the conductor into the terminal opening and tighten the screw firmly using a suitable 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 size matches the 35mm2 specification
• Verify that the DIN rail type is compatible with the mounting mechanism
• Confirm the total number of terminals required for your distribution board layout

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's recommended torque settings to prevent damage to the conductor or the terminal block itself.
