Why Choose the ABB PBHB3121 System pro E Power Insulated Busbar Supports?
The ABB PBHB3121 is a set of 24 insulated busbar supports, each with a nominal length of 100 mm, designed for use within compatible ABB System pro E Power low-voltage electrical distribution switchboards. These components provide mechanical support and electrical insulation for busbar arrangements, helping panel builders construct organised and dependable power distribution assemblies.
As part of the ABB System pro E Power range, the PBHB3121 supports the installation of busbar systems within modular electrical switchboards. Insulated supports are essential components in properly engineered busbar assemblies, helping maintain conductor positioning and separation from associated metal structures.
Supplied as a set of 24 supports, the PBHB3121 provides a practical solution for electrical panel builders and switchboard manufacturers requiring consistent support components. The 100 mm nominal length identifies the support size, allowing selection for compatible ABB System pro E Power busbar configurations.

Insulated Mechanical Support for Electrical Distribution Busbars
The ABB PBHB3121 is intended for the mechanical support of busbars within compatible low-voltage electrical distribution assemblies. Busbars carry electrical power between incoming supplies, switching devices and outgoing distribution circuits, making correct positioning and mechanical support important considerations in switchboard design.
The insulated support arrangement helps maintain separation between conductive busbars and adjacent structural components. Correctly selected and installed busbar supports also contribute to the mechanical stability of an assembly, particularly where conductors must remain securely positioned during normal operation.
The 24-piece supply quantity makes the PBHB3121 suitable for switchboard projects requiring multiple matching support components. Each support has a nominal length of 100 mm, allowing electrical panel builders to identify the specified ABB component when planning compatible busbar installations.
Busbar support selection must account for the complete assembly design, including conductor dimensions, support spacing, electrical clearances and prospective short-circuit forces. The PBHB3121 should therefore be installed according to the applicable ABB System pro E Power assembly instructions rather than assigned an independent current rating or short-circuit withstand rating.
Typical Applications
- ABB System pro E Power low-voltage electrical switchboards.
- Modular power distribution cabinet assemblies.
- Industrial electrical distribution systems.
- Main low-voltage distribution boards.
- Commercial building electrical switchboards.
- Busbar mounting and mechanical support arrangements.
- Internal electrical distribution conductor assemblies.
- OEM electrical panel building and switchboard manufacturing.
- Industrial electrical switchroom installations.
- Compatible busbar system maintenance and refurbishment.
- Replacement of matching insulated busbar support components.
