This document lists standard electrical power system device function numbers from ANSI C37.2. It includes 99 device functions numbered 1 through 99 with
Understanding ANSI standard relay numbers is crucial for anyone involved in electrical protection and control systems. These numbers, defined by the ANSI/IEEE C37.2 standard, provide a standardized
Protective relays are commonly referred to by standard device numbers. For example, a time overcurrent relay is designated a 51 device, while an instantaneous overcurrent is a 50 device.
suffix letter or number may be used with the device number; for example, suffix N is used if the device is connected to a Neutral wire (example: 59N in a relay is used for protection against Neutral
