Industrial 58-301 300:5A Current Transformer

Industrial 58-301 300:5A Current Transformer from the Flex-Core family is a current-sensing device designed to convert high AC currents into a 5 A secondary signal for instrumentation and protection circuits. With a primary rating of 300 A and a secondary rating of 5 A, it provides a 60:1 turns ratio, enabling safe, accurate monitoring of large currents by meters, relays, and protection equipment in electrical panels and industrial systems. This current transformer is commonly used in electrical distribution and energy-management applications where continuous monitoring of line current is required and where a 5 A output is routed into standard measuring devices or protection equipment. The 300:5 A specification is a common standard for instrumentation CTs, promoting compatibility with a broad range of meters and protective relays in industrial environments.
