Why Choose the ABB S204M-K0.3UC Miniature Circuit Breaker?
The ABB S204M-K0.3UC is a compact four-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in AC and DC electrical installations. As part of the ABB System pro M compact S200M series, it combines a K tripping characteristic with universal-current operation for flexible use across industrial and electrical distribution systems.
The S200M UC range is designed for applications requiring circuit protection on both alternating and direct current systems. Its universal-current design supports AC and DC operation, while the K tripping characteristic is suited to circuits requiring protection where higher permissible inrush currents can occur.
With a 0.3 A rated current, K tripping characteristic, four-pole configuration and 10 kA rated breaking capacity, the S204M-K0.3UC is suitable for low-current control, instrumentation and industrial circuits where dependable AC/DC circuit protection and compact DIN-rail installation are required.
