Why Choose the ABB S201M-K3 Miniature Circuit Breaker?
The ABB S201M-K3 is a high performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the ABB System pro M compact S200M series, this modular circuit breaker provides dependable protection for commercial, industrial and OEM electrical installations.
This miniature circuit breaker features a K curve tripping characteristic, making it suitable for circuits with moderate to high inrush currents. It is commonly used for inductive loads, transformers, relays, control circuits and industrial equipment where reliable protection and nuisance-trip resistance are required.
With a rated current of 3 A, 230 / 400 V AC rated operational voltage and a 10 kA short-circuit breaking capacity, the S201M-K3 provides robust protection for low-current circuits. Its compact one-module format enables efficient DIN rail installation inside distribution boards, machinery panels and control cabinets.

Reliable Circuit Protection for Industrial Applications
Miniature circuit breakers automatically disconnect electrical circuits during overload or short-circuit conditions, helping prevent damage to wiring, equipment and connected loads. K curve breakers provide a higher magnetic trip threshold than standard B and C curve devices, making them useful where brief inrush currents may occur during normal operation.
The ABB S200M range is widely used by electrical contractors, panel builders and OEM manufacturers thanks to its robust construction, modular design and compatibility with ABB System pro M accessories. The S201M-K3 is well suited to low-current circuits where dependable protection and compact installation are required.
Typical Applications
- Industrial control panels.
- Transformer and relay circuits.
- Automation equipment.
- Low-current auxiliary circuits.
- OEM machinery and equipment.
- Commercial distribution boards.
