Installations utilizing both aluminum and copper conductors
Projects requiring integration with flexible busbar systems
When it may not be suitable
This terminal block is not intended for use with conductors smaller than 95mm2, as the clamping mechanism is specifically calibrated for larger cross-sections. It is also not suitable for environments where the voltage exceeds the rated 1000V AC or 1500V DC limits.
Key specifications
Conductor range: 95-300mm2
Material compatibility: Aluminum and Copper
Busbar compatibility: 6x1x40mm
Rated voltage: 1000V AC / 1500V DC
Color: Grey
How to use
To install the MOREK OTL300-3B, ensure the power supply is completely disconnected. Strip the insulation from the conductor to the appropriate length and insert it into the terminal opening. Tighten the screw mechanism to the manufacturer's specified torque to ensure a secure and low-resistance connection. If using a flexible busbar, align it correctly with the designated input slot before securing. Verify that the connection is firm and that no loose strands are visible before energizing the system.
What to consider before purchase
Verify that your conductor cross-section falls within the 95-300mm2 range.
Confirm that your system voltage does not exceed 1000V AC or 1500V DC.
Ensure the physical space in your enclosure is sufficient for the terminal block dimensions.
Check that your busbar dimensions match the 6x1x40mm specification.
Usage recommendations
Always use calibrated torque tools during installation to prevent damage to the terminal or the conductor. Regularly inspect the connection points in high-vibration environments to ensure long-term stability and safety.
