ABB S202-K1A Low Voltage Molded Case Circuit Breaker

ABB S202-K1A Low Voltage Molded Case Circuit Breaker is a two-pole molded case protective device from ABB’s S200 family, configured for 230/400 VAC operation with a nominal current rating of 1 A. The unit features a curve K tripping characteristic and a short-circuit current rating of 6 kA, enabling it to interrupt fault currents in small-draw or control circuits. As part of ABB’s S200 molded case circuit breaker lineup, the S202 family provides low-voltage protection with compact form factors suitable for distribution panels and control gear. The S202-K1A variant is documented in ABB catalogs and distributor listings as a 1 A, 2-pole, K-curve device within the S202 series, reinforcing its role in protecting branch circuits against overcurrent at 230/400 VAC. With these specifications, practitioners select the S202-K1A for applications requiring reliable, immediate interruption of overcurrent on modest-load circuits while maintaining ABB’s standard of electrical safety and interoperability.
