ABB S1N-15A-480Y/277V-3P Circuit Breaker

ABB S1N-15A-480Y/277V-3P circuit breaker is a three-pole protective device from ABB rated at 15 amperes for 480Y/277V AC systems. It interrupts all three phases simultaneously in fault conditions, delivering reliable overcurrent protection for three-phase branch circuits in commercial and industrial power distributions. With a 15A rating, it suits circuits where load currents stay within this limit while guarding equipment against short circuits and overloads. Designed for installations in 480Y/277V networks, this breaker helps coordinate protection within ABB’s range of protective devices used in panelboards and switchgear operating at this voltage level.
