Why Choose the ABB S201M-K3UC Miniature Circuit Breaker?
The ABB S201M-K3UC, order code 2CDS271061R0317, 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 reliable overload and short-circuit protection for industrial electrical, control and direct-current circuits.
Rated at 3 A with a Type K tripping characteristic, the S201M-K3UC is particularly suited to industrial circuits with inductive loads and temporary inrush currents. Its universal-current construction enables use in both AC and DC installations, with operation at 230 V AC and up to 220 V DC in a single-pole configuration.
The S201M-K3UC offers a 10 kA short-circuit breaking capacity and combines compact DIN-rail installation with the flexibility of ABB's System pro M compact® accessory platform. Its universal-current capability and robust construction make it well suited to industrial automation, machinery, transportation and DC distribution applications.
Key Advantages
- Universal AC/DC miniature circuit breaker for industrial applications.
- 3 A rated current for control, auxiliary and branch circuits.
- Type K tripping characteristic suitable for circuits with inductive loads and inrush currents.
- 10 kA short-circuit breaking capacity for robust fault protection.
- Single-pole operation at up to 220 V DC.
- Suitable for standard 230 V AC applications.
- Electrical endurance of up to 20,000 cycles.
- Compatible with the established ABB System pro M compact® accessory range.
Key Features
- ABB S 200 M UC universal-current MCB series.
- Single-pole (1P) configuration.
- 3 A rated current.
- K-curve tripping characteristic.
- 10 kA short-circuit breaking capacity.
- Suitable for AC and DC circuit protection.
- Rated for 230 V AC / 220 V DC applications.
- Thermal-magnetic overload and short-circuit protection.
- IP20 protection rating.
- Operating temperature range of -25 to +55 °C.

Universal-Current Protection for Industrial Circuits
The ABB S201M-K3UC combines thermal overload protection with magnetic short-circuit protection, automatically disconnecting the circuit when excessive current occurs. Its Type K characteristic is particularly useful for appropriate inductive loads where normal starting or energisation currents could cause unwanted operation of a more sensitive breaker characteristic.
The S 200 M UC family is designed specifically for universal-current operation and can therefore protect both AC and DC circuits. The single-pole S201M-K3UC supports DC applications up to 220 V DC, while multi-pole arrangements within the wider S 200 M UC range can be applied to DC voltages up to 440 V DC. Correct polarity must be observed when installing the breaker in 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.
