ABB’s range of busbar IEDs (Intelligent Electronic Devices) provide versatile management of busbar installations with models focused on high-impedance and distributed protection.

Multiple models provide specialist protection depending on the application, with full support for phase-to-phase and phase-to-earth faults and fast clearance across solidly earthed and low-impedence.

As part of ABB’s Relion family of protection and control products the busbar range incorporates the core values of the IEC61850 standard, providing future-proofed technologies backed with ABB’s leading-edge technology and global application knowledge.
