Maritime transport is responsible for approximately 1 billion tons of Greenhouse Gas (GHG) annually, according to figures from theInternational Maritime Organization(IMO). The institution warned in its latest study that if timely measures are not taken, the damage could double by 2050.
In view of this scenario, the electrification of ships has boomed, which are also equipped with advanced technologies to mitigate climate change and offer a high range of innovation.
In this regard, ABB presented in Hamburg, Germany, the Sace Infinitus, the first IEC60947-2 circuit breaker with ultrafast semiconductor technology capable of detecting and eliminating short-circuit faults 100 times faster than a traditional one.
Innovation Details
ABB‘s new model enables marine and transport vessels to operate with sustainable and energy-efficient power grids.
The SACE Infinitus circuit breaker simplifies the integration, protection and control of these new DC grid architectures for ships of all types and sizes.
DC power systems improve fuel efficiency by up to 20%. By eliminating the losses and limitations of AC power, DC grids allow ships to match the electrical output of onboard diesel-electric gensets with the power needed for propulsion and other loads.
DC electrical architectures also simplify the integration of battery storage and hydrogen fuel cell systems into the ship’s electrical system and help maximize efficiency.

Energy Optimization
Infinitus includes protection, switching, isolator, energy meter, network analyzer and intelligent connectivity module; it fits in standard 600 mm electrical panels and integrates seamlessly with ABB‘s Ekip and EPIC software tools for easy configuration.
ABB‘s selected switching technology means that power losses are also up to 70% lower than other power electronics solutions.
It can also be used for other DC distribution applications at industrial sites, in commercial buildings and for electric vehicle charging, using renewable energy and battery storage systems to achieve energy savings and carbon footprint reductions.
