The series NRX low-voltage power circuit breaker is available as an option with the Magnum DS low-voltage, metal-enclosed switchgear. Advantages of the breakers used in this combination include extended contact life through improved fault interruption and open circuit isolation technology; electronic trip innovation including an Arc Flash reduction maintenance system; and breaker-cell mounted communication modules. The breaker’s compact size can accommodate up to eight 800-A frame breakers in a 24-inch-wide structure in traditional ANSI and UL-1558 switchgear; and the breaker can protect up to 65 kA at 480 Vac with SWGR bus bracing at 100 kA standard.
