What We Do

Back to Top

S&C specializes in the switching, protection, and control of electric power systems. Our solutions are an essential part of the electrical grid that brings power to homes and businesses across the world. S&C started with a single product in 1909‒the Liquid Power Fuse. This was the first reliable device able to protect against the high currents in distribution substations. Its invention helped pioneer the widespread adoption and spread of electricity.

Today, we apply our century-long heritage of innovation to address the challenges facing the power grids of today and tomorrow. With a dedicated focus on reliability and resilience, we help reduce the duration of power outages from hours to seconds‒or to no outage at all. We design systems to withstand the impacts of time and nature and help keep the lights on in homes, hospitals, fire stations, and factories around the world.

With more than 100 years of grid expertise, S&C is focused on helping customers make sure their grid is ready for the next 100 years with unparalleled expertise, industry-leading quality, and customer-centered innovation.
