32 A, K-Curve, 1-Pole Supplemental Protector
The ABB S201-K32 is a 1-pole miniature circuit breaker rated at 32 A with a Trip Curve K characteristic, operating at 277 VAC and providing a 6 kA interrupting capacity. It is listed as a UL 1077 supplemental protector within the S200 series, intended for branch-circuit protection in control panels and industrial equipment where a K-curve trip response is specified.
The K-curve (typically 8–12x rated current magnetic trip) is designed for inductive loads such as motors, transformers, and solenoids where moderate inrush is expected but a faster trip than a D-curve is desired.
Deployment Context
As a UL 1077 supplemental protector, it is intended for use within an end-product enclosure (e.g., a control panel or machine) rather than as a service-entrance breaker — the UL 1077 listing certifies overcurrent protection for branch circuits inside equipment, not for the main building feed.
