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

The Simet STB 35 SIMBLOCK is a professional-grade screw-type rail terminal block engineered for secure electrical connections with 35mm2 conductors. Designed to accommodate both aluminum and copper wiring, this component is an essential element for maintaining stable electrical distribution in industrial, commercial, and residential switchgear and distribution boards. Its durable construction and distinct brown finish facilitate organized wiring management and long-term operational reliability.

Advantages

This terminal block offers exceptional versatility by supporting both aluminum and copper conductors, which simplifies inventory management and installation processes. The robust screw-type mechanism ensures a high-pressure contact that minimizes resistance and prevents overheating, contributing to the overall safety of the electrical system. Its compact design allows for efficient space utilization on standard mounting rails, while the high-quality materials ensure resistance to mechanical stress and environmental factors common in electrical enclosures.

Suitable for

• Industrial distribution boards and control panels
• Residential electrical service entrance equipment
• Connecting aluminum and copper power cables
• Modular electrical installations on DIN rails

When it may not be suitable

This terminal block is specifically designed for 35mm2 conductors and may not be suitable for cables with significantly smaller or larger cross-sections. It is intended for use in controlled environments such as distribution boards and should not be exposed to direct outdoor elements without appropriate protective enclosures.

Key specifications

• Conductor capacity: 35mm2
• Compatible conductor materials: Aluminum and Copper
• Connection type: Screw terminal
• Mounting type: Rail-mounted
• Color: Brown

How to use

To install the Simet STB 35, ensure the power supply is disconnected. Secure the terminal block onto the mounting rail until it clicks into place. Strip the insulation from the end of the conductor according to the required length. Insert the conductor into the terminal opening and tighten the screw firmly using an appropriate screwdriver to ensure a secure mechanical and electrical connection. Verify that the wire is held tightly and cannot be pulled out.

What to consider before purchase

• Verify that the conductor cross-section matches the 35mm2 specification
• Ensure the mounting rail type is compatible with the terminal design
• Check local electrical regulations regarding the use of aluminum conductors

Usage recommendations

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