Why Choose the ABB S201M-K5UC Miniature Circuit Breaker?
The ABB S201M-K5UC, order code 2CDS271061R0357, is a high-performance single-pole miniature circuit breaker (MCB) for AC and DC applications. Part of the ABB System pro M compact® S 200 M UC series, it provides dependable overload and short-circuit protection for industrial electrical, control and direct-current circuits.
Rated at 5 A with a Type K tripping characteristic, the S201M-K5UC is suited to industrial circuits where inductive loads can produce temporary starting or energisation currents. Its universal-current construction supports operation at 230 V AC and up to 220 V DC in a single-pole configuration.
The S201M-K5UC provides a 10 kA short-circuit breaking capacity at 220 V DC and 253 V AC, with an ultimate breaking capacity of 20 kA at 110 V DC. Compact DIN-rail construction, international approvals and compatibility with System pro M compact® accessories make it a flexible solution for industrial automation, machinery and DC distribution.
Key Advantages
- Universal AC/DC miniature circuit breaker for industrial applications.
- 5 A rated current for control, auxiliary and branch circuits.

Universal-Current Protection for Industrial Circuits
The ABB S201M-K5UC combines thermal overload protection with magnetic short-circuit protection, automatically disconnecting the circuit when excessive current occurs. Its Type K characteristic makes it particularly useful for suitable inductive loads where temporary starting currents could otherwise result in unwanted operation of a more sensitive breaker characteristic.
The S 200 M UC family is designed specifically for universal-current applications. The single-pole S201M-K5UC supports DC circuits up to 220 V DC, while suitable multi-pole configurations within the wider S 200 M UC range can be applied at up to 440 V DC. Correct device polarity must be observed for DC applications.
Typical Applications
- Industrial AC and DC control circuits.
- Automation and machine control systems.
- Circuits supplying suitable inductive loads.
- DC auxiliary and battery-powered systems.
- Industrial electrical distribution panels.
- Railway and transportation electrical equipment.
- TN and IT electrical systems.
- OEM machinery and control-panel construction.
