Its distinct yellow-green color coding ensures easy identification for grounding circuits within complex electrical systems.
Advantages
This terminal block offers significant benefits for electrical installations, primarily through its spring-cage connection system that eliminates the need for manual screw tightening and reduces maintenance requirements over time. The design provides excellent vibration resistance, ensuring that connections remain stable in demanding industrial environments. Its compact width allows for high-density wiring, while the robust construction ensures long-term operational reliability and safety in grounding applications.
Suitable for
Industrial control cabinet wiring
Grounding applications in automation systems
Electrical distribution panels
Vibration-prone machinery and equipment
When it may not be suitable
This terminal block is specifically designed for grounding purposes and should not be used for phase or neutral power distribution. It is intended for mounting on standard DIN rails and may not be compatible with non-standard mounting surfaces or specialized enclosure types without appropriate adapters.
Key specifications
Connection method: Spring-cage connection
Number of connections: 2
Cross section capacity: 0.08 mm² to 6 mm²

How to use
To install the terminal block, snap it onto the compatible NS 35/7,5 or NS 35/15 DIN rail until it clicks securely into place. Strip the insulation from your conductor according to the required length and insert the wire into the spring-cage opening using a suitable screwdriver to actuate the spring mechanism. Ensure the wire is fully seated to guarantee a secure electrical connection to the rail.
What to consider before purchase
Verify that your DIN rail type matches the NS 35/7,5 or NS 35/15 standards.
Ensure the wire cross-section falls within the 0.08 mm² to 6 mm² range.
Confirm that the 6.2 mm width fits within your existing terminal block assembly.
Usage recommendations
Always ensure that the DIN rail is properly grounded to the main protective earth system to maintain the integrity of the grounding circuit. Periodically inspect connections in high-vibration environments to ensure optimal performance.
