Short Circuit Ratings
Short Circuit Ratings (North America CSA, cUL)
Changes to UL 508A and NEC in recent years have brought a focus to control panel safety with regard to short-circuit current
ratings (SCCR). Eaton’s C440 electronic overload relays combined with XT series IEC and Freedom Series NEMA contactors
provide a wide variety of SCCR solutions needed for a variety of applications. The SCCR data in this document reflects the
latest information as of April 2010.
