Reliance Electric 64670-15R Transformer

Reliance Electric 64670-15R is a current transformer (CT) listed under the Allen‑Bradley/Reliance Baldor lineage, defined by Rockwell Automation as a TRANSFORMER, CURRENT with the part number 64670-15R. This model is referenced in multiple catalogs and vendor listings specifically as a current transformer, and current market notes indicate it has been discontinued by the manufacturer. Today the 64670-15R appears in surplus and used/recertified channels, including retailers such as Relectric and PLCHardware, reflecting its status as a legacy part that may still be sought for replacements in older systems. As a CT, its role is to provide a scaled, low‑current representation of the primary circuit to instrumentation, metering, or protective relays, enabling safe monitoring of AC current without exposing the measuring equipment to high conductor currents. While verified sources confirm its identity as a current transformer and its discontinued status, exact electrical specifications (such as turns ratio, primary/secondary ratings, or voltage class) are not specified in the available listings. This makes it important to verify exact compatibility with your panel hardware, mounting style, and any required secondary burden before purchase.
