Allen-Bradley 01-2471-40 Current Transformer

Allen-Bradley 01-2471-40 Current Transformer (CTM 100) is an instrument current transformer that accurately measures alternating current by stepping down high primary currents to a proportional secondary current suitable for metering, monitoring, and protective relays. With a 100 A primary rating, it is commonly installed in switchgear, motor control centers, and power distribution panels, as well as industrial automation systems, where precise current measurement supports load monitoring, energy metering, and protective relay operation. The CTM 100 provides a proportional secondary current output and is designed for panel or switchgear mounting, ensuring compatibility with power meters, relays, and monitoring systems across industrial and commercial electrical installations. Alternate part number 01-2471-40; Manufacturer CTM / OEM Electrical Components Manufacturer.
