That's the key difference from a Curve C (5–10× In) or Curve B (3–5× In) — if your load has a big magnetizing surge, D is the right call. Lifecycle status is current — no obsolescence notice on this code. In a crowded panel, that single-pole footprint leaves room for adjacent breakers or aux contacts. Rated 277 VAC phase-to-neutral — common for 480Y/277 V wye systems where the breaker protects a single-phase load off one leg.","metaTitle":"S201-D3 MCB 1P D 3A 277VAC 6kA DIN Rail","metaDescription":"S201-D3 miniature circuit breaker, 1 pole, Trip Curve D, 3 A, 277 VAC, 6 kA interrupting rating.
