The 60 V DC rating covers telecom battery banks, solar string combiners, and DC bus distribution in control cabinets — applications where standard AC-rated MCBs may not interrupt a DC arc reliably. Mounts on standard DIN rail. The single-pole format keeps panel width tight; for multi-pole DC circuits (e.g., bipolar 60 V rails), gang two units with the busbar or order the factory-assembled 2-pole variant.","metaTitle":"ABB S201DC-K20 MCB 1P K 20A 60V DC/AC, current lifecycle","metaDescription":"ABB S201DC-K20 miniature circuit breaker, 1-pole K-curve 20A rated for 60V DC/AC.
