Application Note: Determining the Circuit Breaker Size
Application Note: Determining the Circuit Breaker Size 1. Application Note: Determining the Circuit Breaker Size Revision History Version September 2021: Changes in Circuit Breaker criteria table Version July 2021: More info added to Circuit Breaker criteria table Version January 2021: More info added to Circuit Breaker criteria table Version February 2019: release Introduction Inverters should be protected by Circuit breakers. This document describes how to determine which Circuit Breaker to use in three phase commercial installations. Using Transformers in Commercial Three Phase Inverter Installations Using transformers in a commercial installation is optional. In most cases a transformer is used to connect the installation to the medium voltage power grid.
sections in standards such as IEC 60909, IEC 60364, UL 508A and NEC 2017. Some manufacturers provide detailed information about the transformershort circuit calculation procedure, and its effect on the selection of circuit breakers and fuses at the different hierarchical levels of the installation topology (see . Figure 1).
