It mounts on standard DIN rail — snaps into a panel enclosure alongside other S200-series protectors, sharing the same 1-module width per pole. Listed as a UL 1077 supplemental protector and CSA 22.2 compliant. These standards cover branch-circuit overcurrent protection for equipment — not service-entrance or feeder duty. The 6 kA interrupting rating at 277 VAC is tested per UL 1077 requirements.","metaTitle":"S201-K20 Miniature Circuit Breaker, 20A, 1P, Curve K, 277VAC","metaDescription":"S201-K20 miniature circuit breaker, 20 A, 1-pole, Trip Curve K, 277 VAC, 6 kAIC.

The difference is the trip curve: K vs. C.
