Suitable for
Industrial power distribution systems
Electrical panel installations
Connecting large cross-section aluminum or copper cables
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 cable sizes. It is also not suitable for applications exceeding the specified voltage ratings of 1000V AC or 1500V DC.
Key specifications
Conductor range: 95-300mm2 (Al/Cu)
Number of connections: 3
Busbar compatibility: 6x1x40mm
Voltage rating: 1000V AC / 1500V DC
Color: Blue
How to use
Installation should be performed by a qualified professional in accordance with local electrical regulations. Begin by ensuring the power supply is disconnected. Strip the insulation from the conductors to the appropriate length and insert them into the terminal ports. Tighten the screws to the recommended torque to ensure a secure mechanical and electrical connection. When using a flexible busbar, ensure it is properly aligned with the designated input slot before securing.
What to consider before purchase
Verify that your conductor cross-section falls within the 95-300mm2 range.
Ensure the installation environment complies with the 1000V AC/1500V DC rating.
Check the physical space available in your electrical cabinet to accommodate the terminal dimensions.
Usage recommendations
Always use calibrated torque tools during installation to prevent damage to the terminal or the conductors, and perform a final inspection of all connections to ensure they are tight and properly seated.
