## Long description

The MOREK OTL150-3 is a high-quality screw terminal block engineered for the secure connection of both aluminum and copper conductors. With a capacity range of 25mm2 to 150mm2, this terminal block is specifically designed for grounding applications, featuring a distinct yellow-green color for easy identification within electrical panels and distribution systems. Its robust construction ensures reliable electrical contact and long-term durability in demanding environments.
Advantages
This terminal block offers exceptional versatility by allowing the direct connection of aluminum and copper wires, which simplifies installation processes in mixed-material electrical systems. The screw-type mechanism provides a high-pressure, low-resistance connection that maintains stability over time, reducing the risk of overheating or loose contacts. Its compact design saves valuable space in enclosures while the clear color-coding enhances safety and maintenance efficiency by clearly marking the grounding circuit.
Suitable for
Grounding systems in industrial electrical cabinets
Residential electrical distribution boards
Connecting aluminum and copper power cables
Infrastructure projects requiring reliable earth connections
When it may not be suitable
This terminal block is not intended for use with conductors outside the specified 25mm2 to 150mm2 range, as improper sizing can lead to poor electrical contact or mechanical failure. It is also not designed for high-vibration environments where specialized vibration-proof connectors might be required.
Key specifications
Conductor range: 25mm2 to 150mm2
Material compatibility: Aluminum and Copper
Color: Yellow-Green
Connection type: Screw terminal
How to use
To install the MOREK OTL150-3, ensure the power supply is disconnected. 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 securely using the appropriate tool to ensure the wire is firmly held in place. Verify the connection by gently pulling on the wire to ensure it is locked. Always ensure that the torque applied matches standard electrical installation practices to prevent damage to the terminal or the conductor.
What to consider before purchase
Verify the cross-sectional area of your conductors falls within the 25-150mm2 range.
Confirm the terminal block is compatible with your specific mounting rail or enclosure type.
Ensure the yellow-green color meets your local regulatory requirements for grounding identification.
Usage recommendations: Regularly inspect the terminal connections during routine maintenance to ensure screws remain tight, especially in installations subject to thermal expansion and contraction.
