At 8 A it protects a 1.5 mm² copper conductor circuit at 277 VAC, which covers control transformers, small VFD input feeds, and lighting contactor coils in a standard panel layout. ## Active production — sourcing and lifecycle Quoted to order against the BOM quantity — availability and pricing confirmed at RFQ through independent industrial distribution.","metaTitle":"ABB S202-D8 2-Pole MCB, Trip Curve D, 8 A, 277 VAC","metaDescription":"ABB S202-D8 miniature circuit breaker, 2-pole, 8 A, Trip Curve D, 277 VAC, 6 kA interrupting rating.

Both share the same 2-pole DIN rail footprint, 277 VAC rating, and 6 kA interrupting capacity, so the S202-D8 drops into the same panel slot without rewiring. Choose Curve D when the load has a high starting surge (motors, transformers); choose Curve C for general resistive or electronic loads."},{"question":"What compliance documentation does ABB provide for the S202-D8?","answer":"ABB supplies a Declaration of Conformity covering IEC/EN 60898-1 and IEC/EN 60947-2, plus material compliance statements for RoHS and REACH. The breaker carries CE and UKCA marking for European markets; UL 1077 recognition is available on the S200 series.
