Functions
The additional neutral busbar 160 A is intended to complement high-power distribution busbars by providing extra neutral connection points. It increases distribution capacity in high-current installations while ensuring appropriate electrical withstand.

Applications
Suitable for industrial and commercial high-power installations requiring a large number of connections. Used as a complement to 160 A distribution busbars in switchboards, main distribution panels and multi-feed installations.

Usage recommendations

• Respect the permissible cable cross-sections for each terminal type.
• Apply a tightening torque of 2 to 3 Nm to ensure reliable electrical contact.
• Disconnect power before any intervention.
• Use ferrules for flexible cables to ensure an optimal connection.
• Regularly check terminal tightening and the general condition of the busbar.
• Do not exceed rated current and short-circuit withstand values (Icc and Icw).
