The document lists various devices and relays used in electrical systems, including their functions such as starting, stopping, and monitoring. It includes terms like ''master contactor'', ''overspeed device'',
In the design of electrical power systems, the ANSI Standard Device Numbers denote what features a protective device supports (such as a relay or circuit breaker). These types of
To assist the Protection Engineer in converting from one system to the other, a select list of ANSI device numbers and their IEC equivalents are given in the following figure.
In this article, I combined all the main IEEE/ANSI definitions for protection elements, possible extensions, and meanings behind them. Feel free to share and spread the knowledge.
Here is a table that lists most of the ANSI codes for electrical protection relays, along with their description and corresponding IEC standards, highlighted in bold are the most common
The protection and control devices in electrical equipment can be referred to by numbers, with appropriate suffix letters when necessary, according to the functions they perform.

In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments.
This ANSI protection code list provides an overview of standards used in various relays, including but not limited to overload protection relays, general-purpose relays, and more.
