As railway systems and standards have changed, so have the protection needs. Eaton’s Bussmann business is continually developing new and improving existing designs to meet these ever changing requirements. The experience of Eaton’s Bussmann business in protecting semiconductor devices has proved invaluable as train systems have moved to power based converters for the variable speed motor drives and also for auxiliary power conversion.
