Consolidate Up to 48 Termination Positions

With 48 specified holes, the NB-48 offers the greatest connection count in Tesla's 165A NB brass bar range. It is intended for designs that need more positions than the NB-36 can provide or that deliberately include additional termination capacity.

Each hole is specified at 10mm². The bar also incorporates two M8 bolts with spring washers. These details allow the product to be assessed against the circuit count, conductor requirements and current rating established for the electrical assembly.

Check the 440mm Length Before Ordering

The NB-48's high capacity requires the largest mounting footprint in the range. Its 440mm length is 124mm greater than the NB-36, so accurate measurement is important. Allow suitable space for the bar, its mounting arrangement, conductor bends and ongoing access to the terminations.

Selecting the highest hole count isn't always the most efficient option. If fewer positions are required, the NB-36, NB-24, NB-18 or NB-12 may provide a closer match and require less enclosure space. The NB-48 is best considered where its full capacity or planned spare positions provide a clear benefit.

Tesla identifies this product for both earth and neutral applications. The installation design must determine how the bar is mounted and whether insulating components are needed. Mounting accessories aren't specified as part of the supplied product information.
