It is classified as a UL 1077 supplemental protector — meaning it protects downstream equipment, not the branch circuit itself, so it goes after a listed branch-circuit overcurrent device. Listed under UL 1077 (Supplemental Protectors) and CSA 22.2 No. 235. RoHS and REACH compliance documentation is standard with the shipment. For IEC-rated applications, check the corresponding S200 series IEC version. ## Panel integration The 2-pole width occupies two module spaces (36 mm). Torque to 2.5 Nm. No busbar bridging required for single-pole protection; for multi-pole ganged switching, use the S200 series busbar comb.","metaTitle":"S202-K6 ABB S200 Series 6A K-Curve 2-Pole DIN Rail MCB, 277V","metaDescription":"ABB S202-K6 6A, K-curve, 2-pole DIN-rail miniature circuit breaker. 277VAC, 6kA interrupting.

This is the maximum fault current the breaker can safely interrupt under UL 1077 testing. For higher available fault currents, a current-limiting upstream device or a higher-rated series is needed."},{"question":"What compliance documentation does ABB provide for S202-K6?","answer":"RoHS and REACH declarations are standard.
