New UL protection devices include an “industry first” UL 489 Branch Circuit Breaker with Ground Fault Relay (GFL Series) that combines a ground fault equipment protector with a UL 489 branch circuit protector, which eliminates a need for upstream circuit protection. UL 1053 Ground Fault Sensing and Relaying Device (GF Series) provides residual current protection for circuits with loads up to 63 A, and UL 1077 Ground Fault Relay with Overload Protection (GFR Series) serves as a combined equipment ground fault relay and supplementary protector (RCBO). All three series offer ground fault sensitivity levels from 10-500 mA.
