Celebrating a milestone in electrical safety, ABB this year marks the 100-year anniversary of its miniature circuit breaker (MCB). Since it was launched, the MCB has been safeguarding electrical circuits and enabling a safer world. Looking ahead on the journey towards a net-zero future, ABB celebrates its MCB as an innovation, today enabling the integration of renewable energy sources and still ensuring consistent protection against electrical hazards.
ABB’s S800P series miniature circuit breakers offer a compact and reliable solution for line protection up to 50 kA.
Ettienne Delport, Vice President of Electrification - Smart Buildings, Smart Power at ABB, reflects on the significance of this milestone. "As we transition towards a net-zero future, it is essential to increase electrification and integrate more diversified, renewable energy sources. ABB provides electrical safety for equipment ranging from solar panels and heat pumps to electric vehicles and brings additional protection against faults like residual currents, surges, earth fault currents, or arc faults."
The evolution of the MCB demonstrates ABB's commitment to excellence and innovation. In 1924, Hugo Stotz and Heinrich Schachtner pioneered the first resettable MCB – and today it is produced around the world.
In this product line, ABB has continuously set industry standards for performance, compact size, connectivity, and transparency. Core to its MCB is a combination of cutting-edge technology and its dedication to safety. With the ability to detect electrical faults within milliseconds, the MCB ensures swift intervention, mitigating potential risks and preventing catastrophic events. It is also designed to streamline installation processes and to make installation easy for professionals and technicians with different skills levels.
ABB’s MCBs are used in multiple diverse applications, including factories and data centres, protecting lives and safeguarding assets reliably.
