Satisfying every possible plant engineering need

Critical applications, such as hospitals, airports, communications systems and data centers, require a constant and reliable power supply to keep fundamental services running and prevent serious consequences due to power interruption. This need is even stronger nowadays since increased capacity of these systems is required. In order to ensure end-to-end reliability, the system must include backup generators and UPS which ensure the power supply to the critical loads in case of outages from the grid.

Emergency or standby power systems are fundamental in many industrial and building applications requiring a constant power supply. Backup generator sets are installed to temporarily provide power to the facility when the primary source fails.

ABB can offer genset OEMs a complete range of products, including components for installation in control panels and machines as well as solutions for distribution systems. All the automatic network generator set transfer functions can be provided by ABB products in addition to specific protection suited to generator paralleling switchgear.
