What the ratings mean for fit
The S201-K6 is a 1-pole miniature circuit breaker rated 6 A continuous, with a Trip Curve K characteristic that trips between 8× and 12× rated current — designed for motor and inductive loads where short inrush spikes must pass without nuisance tripping. The 6 kA interrupting capacity at 277 VAC (phase-to-neutral on a 480Y/277 V system) covers most branch-circuit fault levels in North American control panels. Mounts on standard DIN rail, so it swaps into an existing S200-series slot without panel rework.
Compliance and approvals
UL 1077 listed as a supplementary protector and CSA 22.2 certified — accepted for use in UL 508A industrial control panels and Canadian installations. RoHS and REACH compliance documentation is standard with the brand; request it with the RFQ.
