Replacement circuit breakers interrupt and clear large fault currents quickly, providing protection from arc flash incident energy that is comparable or better than fuse-protected circuit breakers. The breakers are available in either Low Arc Flash NW or NT, or for retrofit into existing equipment, for most manufacturers’ 600-volt ANSI switchgear.

Self-testing ground fault receptacles continually test themselves every 60 seconds to verify that they are fully operational, while still providing proper ground fault protection. In addition, units quickly notify the user if ground fault protection has been compromised or if a ground fault condition exists. Available in commercial grade, hospital grade and blank face, standard features include a 10,000-amp short circuit rating and full compliance with UL943 changes scheduled to take effect July 1, 2006.For more about Circuitpro from Bryant, click here .
