The ABB S201P-K6 is a 1-pole miniature circuit breaker rated 6 A with a Trip Curve K characteristic, designed for DIN-rail mounting in distribution boards and control panels. It interrupts fault currents up to 10 kA at 277 VAC, covering the typical line-to-neutral voltage on 480Y/277 VAC systems.
Curve K — what it means on the panel
Trip Curve K is the middle ground between B and C curves: magnetic trip at 8–12× rated current (48–72 A for this 6 A breaker).
