Series sourcing
Eaton TR timing relays parts
Selected Eaton TR timing relay references for exact-code sourcing. Review control voltage, timing range, function and output contact arrangement against the actual control circuit. A common timing range does not establish equivalent wiring or behavior.
Identify the exact unit before sourcing
Use the full manufacturer part number, suffix, revision, firmware, and nameplate details where they affect the requested identity. A product-family match alone does not establish compatibility.
Compare these model references to the installed label. They do not describe current stock or pre-approved replacements.
