Why Choose the ABB PTHS4290 Horizontal Busbar Segregation Panel?
The ABB PTHS4290 is a dedicated horizontal busbar segregation component designed for compatible ABB System pro E Power low-voltage switchboards. Specified for switchboard sections measuring 400 mm wide and 900 mm deep, this accessory supports the physical separation of busbar areas within modular electrical distribution assemblies.
As part of the ABB System pro E Power modular switchboard system, the PTHS4290 helps electrical panel builders organise internal busbar arrangements and establish defined boundaries between designated switchboard sections. Its horizontal segregation configuration supports structured electrical distribution cabinet construction, particularly where dedicated busbar compartment separation is required.
The PTHS4290 is specified as a horizontal busbar segregation component without the internal upper arrangement, with the additional D configuration, corresponding to the manufacturer's designation SEG.BUS.HOR. NO INT.UP.+D. Its 400 × 900 mm nominal width and depth make it suitable for compatible System pro E Power switchboard sections requiring this specific segregation arrangement.

Purpose-Designed Horizontal Busbar Separation for Modular Switchboards
Busbar segregation components are important elements of low-voltage switchboard construction where physical separation between internal functional areas is required. They help establish defined boundaries around busbar systems, supporting organised layouts and the implementation of specified internal separation arrangements.
The ABB PTHS4290 provides a dedicated horizontal busbar segregation solution for compatible System pro E Power assemblies. Its specified 400 mm width and 900 mm depth allow it to be incorporated into appropriately configured switchboard sections, while the NO INT.UP.+D designation identifies the intended variant within ABB's modular segregation accessory range.
The PTHS4290 is an individual segregation accessory rather than a complete busbar system or switchboard partitioning assembly. The required form of internal separation, electrical clearances, temperature-rise performance and overall assembly compliance depend on the complete switchboard design and correct installation of all compatible components.
Typical Applications
- ABB System pro E Power low-voltage switchboards.
- Horizontal busbar segregation in modular electrical distribution assemblies.
- Switchboard sections with a nominal width of 400 mm and depth of 900 mm.
- Compatible busbar compartment separation arrangements.
- Main low-voltage distribution boards in industrial facilities.
- Commercial building electrical distribution systems.
- Switchboards requiring defined internal functional compartments.
- Electrical panel manufacturing and modular switchboard construction.
- Compatible switchboard modifications and internal segregation installations.
