EM Group ZSG Screw Terminal Block 35 / 50mm2 Yellow-Green

The EM Group ZSG screw terminal block is a professional-grade component engineered for secure and reliable electrical connections in rail-mounted systems. Designed to accommodate conductors with cross-sections of 35mm² to 50mm², this terminal block features a robust screw connection mechanism that ensures high mechanical stability and excellent electrical conductivity. Its distinct yellow-green color coding makes it specifically suitable for protective earth (PE) grounding applications in various industrial and commercial electrical panels.

Advantages

This terminal block offers exceptional durability and ease of installation in standard DIN rail configurations. The high-quality materials used in its construction provide long-term resistance to vibration and thermal stress, ensuring that connections remain secure over extended periods of operation. The design facilitates efficient wiring management, allowing for quick and reliable assembly in complex electrical distribution systems while maintaining strict safety standards for grounding circuits.

Suitable for

• Grounding connections in industrial control panels
• Electrical distribution systems in commercial buildings
• Rail-mounted wiring configurations
• Professional electrical installations requiring high-capacity grounding

When it may not be suitable

This terminal block is not intended for use with conductors outside the specified 35mm² to 50mm² range, as smaller or larger wires may not achieve a secure connection. It is also not designed for environments with extreme chemical exposure or high-moisture conditions unless housed within an appropriate protective enclosure.

Key specifications

• Conductor capacity: 35mm² to 50mm²
• Connection type: Screw terminal
• Color: Yellow-Green
• Mounting type: DIN rail

How to use

To install the terminal block, snap it onto the standard mounting rail until it clicks into place. Strip the insulation from the end of your grounding conductor, insert the wire into the terminal opening, and tighten the screw securely using a compatible screwdriver. Ensure the wire is fully seated and that the connection is firm before applying power to the system. Always verify that the terminal is correctly aligned with other components on the rail to maintain an organized wiring layout.

What to consider before purchase

• Verify that your conductor size falls within the 35mm² to 50mm² range
• Ensure the mounting rail type is compatible with standard terminal block dimensions
• Confirm the total number of grounding points required for your specific installation

Usage recommendations

Always use the correct torque settings when tightening the screw terminals to prevent damage to the conductor or the terminal block itself. Regular inspections of the connections are recommended in high-vibration environments to ensure long-term integrity.
