Its 6 kA interrupting capacity at 277 VAC (phase-to-neutral on a 480Y/277 V system) tells you it safely clears faults up to that level — enough for most commercial and light industrial distribution panels where the available fault current stays under 6 kA. Snaps onto standard DIN rail, so it integrates into any 35 mm rail-mounted sub-distribution board or control panel without extra hardware. This breaker lands in a 3-phase 480Y/277 VAC sub-panel feeding lighting contactors, small HVAC contactors, or control power transformers — loads where the C-curve handles the inrush without tripping and the 6 A rating matches the branch circuit. The 3-pole construction means it simultaneously breaks all three phases on a fault, which is required for any 3-phase load — single-phase branch circuits would use a 2-pole or 1-pole variant.","metaTitle":"S203-C6 Miniature Circuit Breaker, 6A, 3-Pole, Curve C, DIN","metaDescription":"ABB S203-C6 miniature circuit breaker, 6 A, 3-pole, Trip Curve C, 6 kA interrupting capacity at 277 VAC.
