ABB S201UDC-K6 is a DC miniature circuit breaker (MCB) from ABB’s S201UDC family, designed for DIN-rail mounting in DC control panels. The K6 variant is a 1-pole device rated for 6 A at 60 V DC and features a K-curve trip characteristic, intended for DC applications and UL 489 compliance. This MCB provides overcurrent protection for 60 V DC circuits in industrial automation and machinery, and is a common choice in panel builds requiring compact, reliable DC protection.
