By facilitating a clean and orderly arrangement of conductors, it significantly improves the maintainability and safety of electrical distribution boards.

Suitable for

• Industrial electrical panels and control cabinets
• Residential and commercial power distribution systems
• Installations requiring the connection of aluminum and copper conductors
• Projects where space-saving wiring organization is a priority

When it may not be suitable

This distribution block is not intended for use in environments exceeding its rated electrical capacity or in applications involving conductors outside of the specified gauge range. It should not be used in high-vibration environments without appropriate enclosure protection or in areas exposed to direct moisture or corrosive chemical agents.

Key specifications

• Compatibility: Aluminum and copper conductors
• Color: Blue
• Application: Electrical power distribution
• Design: Universal terminal block

How to use

To use the Simet SUB 490, ensure that the power supply to the circuit is completely disconnected before beginning any installation work. Strip the insulation from the ends of the aluminum or copper conductors according to the required length. Insert the conductors into the designated ports of the distribution block and tighten the screws securely to ensure a firm mechanical and electrical connection. Verify that all connections are tight and that no loose strands are visible before restoring power to the system.

What to consider before purchase

• Verify the cross-sectional area of your conductors to ensure compatibility
• Check the total current load of your circuit against the block specifications
• Ensure the installation environment meets the requirements for standard terminal blocks

Usage recommendations

Always use appropriate tools for tightening the terminal screws to prevent damage to the block or the conductors. Regularly inspect the connections during routine maintenance to ensure they remain secure over time.
