Why Choose the ABB PS 3/57/18 CB 3-Phase Busbar?
The ABB PS 3/57/18 CB is a robust three-phase pin busbar designed for efficient cross-wiring of compatible modular protection devices in industrial electrical distribution systems. As part of the ABB System pro M compact PS...CB busbar range, it provides a practical solution for distributing three-phase power across multiple miniature circuit breakers and compatible fuse-disconnector devices.
This busbar features 57 pins, an 18 mm² conductor cross-section and a standard 17.6 mm pin pitch. Its L1, L2 and L3 configuration enables balanced three-phase distribution across compatible devices, while the cuttable design allows the busbar to be adapted to suit different panel layouts and installation requirements.
With a rated uninterrupted current of 80 A, a maximum rated operational voltage of 600 V AC/DC for UL/CSA applications and a 10 kA short-time withstand current, the PS 3/57/18 CB is engineered for dependable industrial power distribution. Its approximately 1005 mm length accommodates up to 19 compatible devices, helping reduce individual wiring and simplify control-panel assembly.

Efficient Three-Phase Distribution for Modular Protection Devices
Busbars such as the ABB PS 3/57/18 CB provide a common conductive path across compatible modular devices, eliminating much of the individual jumper wiring otherwise required in electrical panels. This can reduce installation time, simplify wiring and create a cleaner, more consistent three-phase distribution arrangement.
The PS...CB range is designed for industrial protection applications and includes busbars suitable for cutting to the required installation length. The PS 3/57/18 CB combines its 57-pin layout with an 18 mm² conductor cross-section and high-current capability, making it suitable for substantial modular distribution assemblies using compatible ABB protection equipment.
