The ABB S202-K6 is a 2-pole DIN-rail miniature circuit breaker from the S200 series, rated 6 A with a K-curve trip characteristic, 277 VAC, and 6 kA interrupting capacity. 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.
