Our Global Short-circuit Current Ratings (SCCR) Tool provides coordinated high-fault branch circuit solutions for motor starters, soft-starters, and component drives.
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.
