ESM Chapter 1 Section 230 Equipment and Component IDs - ID Sort Print File - Att 1

Sep 26, 2026

Equipment and component ID list for ESM Chapter 1, Section 230, providing an ID-sorted mapping between numeric codes and specific equipment or component names. The content includes master elements, relays with varied functions (time-delay, checking, interlocking, distance, directional, static breaker failure, protection types), contactors, circuit breakers, switching devices, detectors, governors, transmitters, monitoring and control mechanisms. It further defines many shorthand/abbreviation identifiers (e.g., alarm, analyzer control, actuator, drum sizes) for standardized labeling.

FAQs

What is the purpose of ESM Chapter 1 Section 230 in this file?

It provides an ID-sorted reference that maps numeric equipment/component codes to standardized equipment and component names.

How are the IDs organized in the document?

The document lists entries in a table where the left column is the numeric ID (Sort) and the right column is the corresponding equipment or component name description.

What kind of abbreviations are included beyond the main equipment/component list?

After the primary ID list, the document includes additional short code definitions for items such as alarms, analyzers, actuators, and other labeled elements.
