• Power branching in electrical cabinets
• Professional electrical installations requiring high current capacity

When it may not be suitable

This terminal block is not intended for residential low-voltage applications where such high current ratings are unnecessary. It is also not suitable for environments with high humidity or corrosive atmospheres unless housed within an appropriate protective enclosure.

Key specifications

• 4-pole configuration
• Rated current: 200A
• 3 outlets per pole
• Outgoing terminal 1: 1.5 to 6 mm² capacity
• Outgoing terminal 2: 6 to 16 mm² capacity
• Compatibility: Flat copper bars and distribution block 0 374 00

How to use

The terminal block is designed for mounting onto flat copper bars or the compatible distribution block 0 374 00. Ensure that the main power supply is disconnected before beginning the installation. Insert the conductors into the appropriate terminals based on their cross-section size, ensuring that the screws are tightened to the manufacturer's specified torque to guarantee a secure electrical connection. Verify that all connections are firm and that no bare wire is exposed outside the terminal housing.

What to consider before purchase

• Verify the current requirements of your electrical system
• Ensure compatibility with existing copper busbars
• Check the cross-section of the cables being used
• Confirm that the installation space is sufficient for the block dimensions

Usage recommendations

Always adhere to local electrical codes and safety regulations when installing power distribution components. It is recommended to perform a thermal inspection of the connections after the initial load is applied to ensure stability.
