Its 10 kA interrupting rating at 277 VAC gives you headroom for fault clearing in most commercial and light industrial panelboards without cascading upstream — that SCCR holds the line on a downstream fault. DIN rail mount snaps into the standard 35 mm rail; three poles fill 3 module widths (17.5 mm each), so factor that into your panel fill before the gland plate. ## Where this MCB fits the line At 6 A per pole, it protects a 1.5 kW motor at 277 VAC single-phase or a 3 kW three-phase motor at 480Y/277 VAC wye configuration (line-to-neutral).","metaTitle":"ABB S203P-C6 MCB 3P C 6A, 10 kA, DIN Rail","metaDescription":"ABB S203P-C6 miniature circuit breaker, 3-pole, 6 A, trip curve C, 277 VAC, 10 kA interrupting rating.
