Global Short Circuit Current Ratings

Global Short Circuit Current Ratings

Product catalog summary
Overview: Rockwell Automation provides global Short Circuit Current Ratings (SCCR) Selection Tables for Component Drive circuits. These tables are designed for common global motor voltages (50/60 Hz) and short circuit current rating fault levels, allowing users to select drive circuit components across a wide range of HP or kW ratings based on voltage and SCCR requirements. The selection process is facilitated by an online tool that guides users to the appropriate SCCR Selection Table and the One-Line Bill of Material for the desired motor rating. The tables comply with IEC and UL standards and are verified by Underwriters Laboratories.
PowerFlex 525 Family: The document outlines the PowerFlex 525 family of AC drives, including PowerFlex 525, 4M, 4, and 750 AC Drives. It also covers branch circuit protection options such as fuses and circuit breakers, and motor starting characteristics for standard and heavy-duty applications. Motor sizes range from 1/2 to 300 Hp and 0.16 to 400 kW.
Global Voltages: The document lists supported global voltages, including 220V, 230V, 380-400V, 415V, 440V, 460V, 500-525V, 575V, and 690V, with frequencies of 50 Hz and 60 Hz.
Available Fault Levels: Fault levels available are 65 kA and 100 kA.
Standard Compliance: The document specifies compliance with UL 508A Standard and High Fault SCCR, UL 508C SC test requirements, IEC 60947-4-1 Type 1 and Type 2 short circuit coordination, and UL listing and certification.
Global SCCR Selection Tool: A new online tool is available at www.rockwellautomation.com/go/etools for accessing the SCCR Selection Tables and related documentation.

Global Short Circuit Current Ratings PowerFlex® Low Voltage AC Drives Global SCCR Solutions: Drive Family: Branch Circuit Protection: • Circuit Breakers Motor Starting Characteristics: • Standard Duty • Heavy Duty Motor Sizes: Global Voltages: Available Fault Levels: Standard Compliance: • UL 508A Standard and High Fault SCCR short circuit coordination Rockwell Automation has developed global SCCR Selection Tables for Component Drive circuits based on common global motor voltages (50/60 Hz) and short circuit current rating fault levels. These tables allow users the capability to select drive circuit components over a wide range of HP or kW ratings based on common voltage and SCCR application requirements. Simply select the proper application to locate the correct SCCR Selection Table, then read the One-Line Bill of Material for the desired motor rating. Both component selection and short circuit coordination is complete. The selection tables are based on and are in most cases covered by third party witness by Underwriters Rockwell Automation accredited test facilities.
