2843690 Cembre DNB125-9 NEUTRAL BAR

Why Choose the Cembre DNB125-9 Neutral Bar?

The Cembre DNB125-9, manufacturer part number 2843690, is a robust 125 A neutral bar designed for organised neutral conductor distribution in electrical panels, switchgear and industrial power distribution systems. Part of the Cembre DNB range, it provides multiple direct screw-clamp connection points within a compact insulated assembly.

The DNB125-9 provides 4 input and 9 output connection points, giving a total of 13 ways. Input connections accommodate low-stranded conductors from 10–25 mm² and flexible conductors from 6–16 mm², while the nine outputs accept low-stranded conductors from 2.5–6 mm² and flexible conductors from 1.5–6 mm².

Designed for an operating current of 125 A, the neutral bar uses a brass conductor body, galvanised-steel clamping components and a transparent polycarbonate insulating body. Direct clamping, captive screws and a specified tightening torque of 2 Nm support secure installation, while CE and UKCA approvals make the DNB125-9 suitable for professional panel-building applications.

Reliable Neutral Distribution for Electrical Panels

Neutral bars provide a centralised connection point for neutral conductors within electrical distribution equipment. The Cembre DNB125-9 combines larger incoming conductor capacity with multiple smaller outgoing connections, enabling installers to distribute a neutral connection efficiently across several circuits while maintaining an organised panel layout.

Its brass conductive body provides effective current distribution, while direct screw clamping securely retains connected conductors. The transparent polycarbonate insulating body protects the conductive assembly while allowing convenient visual inspection during installation and maintenance.

Typical Applications

• Industrial electrical distribution panels.
• Switchboards and switchgear assemblies.
• Control panels and automation cabinets.
• Machinery and production equipment.
• Commercial electrical distribution systems.
• Neutral conductor distribution and termination.
• OEM electrical panel building.
