Why Choose the ABB BB-SU 3/112/10 3-Phase Busbar?
The ABB BB-SU 3/112/10 is a high-capacity three-phase pin busbar designed for efficient cross-wiring of compatible modular circuit protection devices. Developed for the ABB S200C compact MCB range, it provides an organised alternative to individual jumper wiring when distributing three-phase power across multiple protection devices in electrical distribution boards.
This busbar provides a nominal 112-position configuration with a 10 mm² conductor cross-section. ABB specifies the BB-SU 3/112/10 for three-phase distribution and for connection with compatible S200C and DSN201E devices, making it well suited to larger modular assemblies where consistent cross-wiring is required.
The BB-SU 3/112/10 spans 55 modular units and has a net weight of approximately 0.579 kg. Its extended format enables numerous compatible devices to be interconnected from a common three-phase supply, helping reduce wiring time and create a cleaner, more maintainable electrical panel.
