Allen-Bradley 3PT3-60-422FFF Potential Transformer

Allen-Bradley FLEX-CORE 3PT3-60-422FFF Potential Transformer steps a 4,200 V primary down to a 120 V secondary with a 35:1 turns ratio, delivering a safe, isolated voltage signal for metering and protection relays. Built for integration in electrical switchgear and power distribution systems, this transformer supports accurate voltage sensing essential for monitoring, control, and protection schemes. The PRI rating is 4,200 V and the turns ratio is 35:1, yielding a 120 V secondary nominal output suitable for connection to meters, relays, and related instrumentation. The 3PT3-60-422FFF designation identifies the FLEX-CORE design family and the specific tapping configuration used in this unit. Typical applications include panel meters, protective relays, and control circuits in industrial environments and electrical distribution systems where reliable voltage scaling is required. As an Allen-Bradley product, it aligns with Rockwell Automation standards for interoperability with compatible instrumentation and protection schemes.
