1sna399886r2100 – spbo,nt,l

Why Choose the TE Connectivity SPBO.NT.L 1SNA399886R2100 Neutral Bar Holder?

The TE Connectivity SPBO.NT.L 1SNA399886R2100 is a blue neutral bar end-section holder designed for compatible Entrelec SNA terminal block assemblies with a separate neutral busbar. It provides the mechanical support required to position and secure the neutral bar within modular DIN-rail terminal installations.

With a compact thickness of 9 mm, the SPBO.NT.L integrates neatly alongside compatible neutral terminal blocks without unnecessarily increasing the overall size of the assembly. It is intended for use with the Entrelec neutral distribution system and complements the BO3 copper busbar measuring 10 × 3 mm and compatible SFB busbar compression clamps.

For correctly supported neutral-bar installations, the manufacturer specifies a maximum distance of 200 mm between two SPBO.NT.L holders. Its distinctive blue construction provides clear identification within the terminal assembly, making it a practical accessory for industrial control panels, distribution equipment and machine wiring systems.

Key Advantages

• Purpose-designed holder for separate neutral busbar assemblies.
• Supports compatible Entrelec neutral terminal block systems.
• Compact 9 mm thickness minimises additional DIN-rail space.
• Designed for use with the BO3 10 × 3 mm neutral busbar.
• Compatible with SFB1 and SFB2 busbar compression clamps within the corresponding system.
• Distinctive blue colour supports easy identification of the neutral system.
• Manufacturer guidance permits a maximum spacing of 200 mm between adjacent holders.

Secure Support for Separate Neutral Busbars

Separate neutral busbars provide an efficient way to distribute a common neutral potential across multiple terminal positions. The SPBO.NT.L is designed to support this busbar at the end and along compatible terminal assemblies, helping maintain correct positioning and mechanical stability throughout the installation.

When used with the corresponding BO3 10 × 3 mm busbar and compatible SFB compression clamps, the SPBO.NT.L forms part of a modular neutral distribution arrangement. Maintaining no more than 200 mm between two holders provides the support specified by the manufacturer for the neutral bar.

Typical Applications

• Separate neutral busbar support in terminal block assemblies.
• Industrial control-panel neutral distribution.
• Machine-building electrical systems.
• Switchgear and distribution equipment.
• Automation and PLC control cabinets.
• DIN-rail terminal installations using compatible Entrelec neutral terminals.
