Industrial 3-0511-1701-4000A Current Transformer

CTI 3-0511-1701-4000A Current Transformer is an industrial-grade sensor designed for use with the K4000 Air Breaker assembly, delivering reliable high-current measurement in demanding electrical environments. The part number 3-0511-1701-4000A signals a 4000A-class primary rating, making it a compact solution for monitoring large currents in switchgear and metering setups. Typical applications include sensing current in distribution panels and protection circuits where the K4000 system requires a precise secondary signal for protection relays, meters, or data acquisition. Engineered for rugged industrial use, this transformer enables integration with protective relays and energy-management systems, providing consistent current reporting and support for timely fault isolation within heavy-duty power installations.
