Simet STB 50 SIMBLOCK Screw Terminal Block for Al/Cu Conductors, Green

The Simet STB 50 SIMBLOCK is a professional screw-type terminal block engineered for reliable electrical connections in distribution panels and industrial control systems. Designed to accommodate both aluminum and copper conductors, this rail-mounted component ensures high mechanical stability and excellent electrical conductivity. Its robust construction makes it an essential element for demanding electrical installations where secure wire termination is required.

Advantages

The primary advantage of the Simet STB 50 is its versatility in handling different conductor materials, allowing for seamless integration of aluminum and copper wiring within the same system. The screw-type mechanism provides a high-pressure contact that minimizes resistance and prevents loosening over time, even under vibration. Its compact, rail-mounted design optimizes space within electrical enclosures, while the distinct green color helps in identifying specific circuit functions or grounding paths during maintenance.

Suitable for

• Electrical distribution panels
• Industrial automation and control systems
• Power supply installations
• Connecting aluminum and copper conductors in building infrastructure

When it may not be suitable

This terminal block is not intended for use in environments with extreme corrosive gases or high-moisture conditions unless housed in an appropriate IP-rated enclosure. It is also not suitable for applications requiring tool-less push-in connection methods.

Key specifications

• Conductor compatibility: Aluminum and Copper
• Mounting type: DIN rail
• Connection type: Screw terminal
• Color: Green

How to use

To install the Simet STB 50, snap the unit onto a standard DIN rail until it clicks into place. Strip the insulation from the conductor to the recommended length, insert the wire into the terminal opening, and tighten the screw using a compatible screwdriver to the specified torque. Ensure the conductor is fully seated before tightening to guarantee a secure connection.

What to consider before purchase

• Verify the cross-section of your conductors matches the terminal capacity
• Ensure the DIN rail type in your enclosure is compatible
• Check local electrical regulations regarding the use of aluminum conductors

Usage recommendations

Always use a calibrated torque screwdriver to ensure the connection meets the manufacturer's specifications, preventing damage to the terminal or the conductor.
