Our Global Short-circuit Current Ratings (SCCR) Tool provides coordinated high-fault branch circuit solutions for motor starters, soft-starters, and component drives.
Access the Global SCCR Tool
The one-line bill of materials provides coordinated high fault SCCR ratings for all power devices used in the circuit, which saves customers time and effort to find and determine these ratings. The data provided by the Global SCCR tool is based in compliance to IEC and UL standards.
This application guide is intended to provide an overview of North American motor circuit design, based on methods outlined in the NEC. Examples provided are intended to illustrate typical applications and do not cover every exception.
