ABB S271-K8A Molded Case Circuit Breaker With Magnetic Trip

ABB S271-K8A is a molded case circuit breaker with a magnetic trip, delivering compact, reliable overcurrent protection for electrical installations. It is a 1-pole device rated at 8 A and designed for 230/400 VAC operation, featuring a magnetic (instantaneous) trip characteristic (K-Curve) to respond quickly to short-circuit conditions in addition to thermal protection for overloads. Marketed as part of ABB’s S271 family, the S271-K8A provides a space-efficient protection solution suitable for low-volume distribution in panels and enclosures where dependable interruption of fault currents is required. The molded-case construction offers insulation and durability, helping to shield conductors and connected equipment from fault-induced damage and arcing while maintaining predictable trip behavior under varying electrical loads.
