At 25 A and 277 VAC, this breaker handles single-phase or line-to-neutral loads up to that current on a 277/480Y VAC system. Curve C gives you a 5–10× magnetic trip window: a 25 A breaker holds through a 125 A surge but trips fast on a 250 A fault, which suits mixed resistive-inductive loads. The 2-pole width is two modular units (36 mm), same as any S200-series breaker, so it swaps in without re-drilling or re-busing. Wire termination is the standard tunnel clamp — accepts up to 25 mm² conductor.","metaTitle":"S202-C25 Mini Circuit Breaker, 25A, Curve C, 2-Pole, 277V","metaDescription":"S202-C25 miniature circuit breaker, 25A, Trip Curve C, 2-pole, 277 VAC, 6 kA interrupting rating.
