ANSI code Electrical Engineering. Letters are sometimes added to specify the application (IEEE Standard C37.2-2008) In the design of electrical power systems, the ANSI Standard Device Numbers (ANSI /IEEE Standard C37.2) denote what features a protective device supports (such as a relay or circuit breaker)

ANSI Device Numbers PDF Relay Switch. The widely used United Sates standard ANSI/IEEE C37.2 'Electrical Power System Device Function Numbers, Acronyms, and Contact Designations' deals with protective device function numbering and acronyms. ANSI/IEEE Standard Device Numbers In North America protective relays are generally referred to by standard device numbers
