The ABB S201C series is a line of single-pole C-type miniature circuit breakers designed for electrical protection in residential and light commercial applications. These breakers are commonly found in panelboards and distribution boards, providing overcurrent and short-circuit protection for individual circuits. If you're working on projects that require reliable circuit protection without the need for additional components, these breakers are a solid choice.

One thing worth noting is their compact design, which makes them ideal for spaces where mounting area is limited. Engineers tend to reach for this when they need a straightforward solution that doesn’t compromise on safety but also doesn’t take up too much space. Another practical benefit is their ease of installation and maintenance—these breakers are designed to be easily accessible for quick replacement if needed. They also come with a clear indication of tripping status, which helps in diagnosing issues quickly.
