Functions and applications
Bipolar distribution blocks 125 A are used to distribute power from a main feed to multiple outgoing circuits. Designed for even current distribution, they feature a high-conductivity copper block to minimize losses and withstand electrical stress. The bipolar design permits simultaneous management of phase and neutral. Compliant with EN 60947-7-1.

• Applications: low-voltage residential, commercial and industrial installations; electrical enclosures; sub-distribution boards; multi-circuit installations.

Usage advice

• Respect the admissible cable cross-sections for each terminal.
• Apply a tightening torque of 2 to 3 Nm.
• Disconnect power before any intervention.
• Use ferrules on flexible cables to ensure secure clamping.
• Check connection tightening periodically.
