ABB S203-C13 3-Pole 13 A C-Curve Miniature Circuit Breaker, 6 kA, 230/400 V AC 2CDS253001R0134

Protect three-phase circuits from overload and short-circuit with the ABB S203-C13 miniature circuit breaker. This 3-pole MCB is rated for 13 A with a C tripping characteristic, making it suitable for loads with moderate inrush currents such as motors, lighting, and control circuits. Its 6 kA breaking capacity ensures reliable interruption of fault currents in residential and commercial installations.

Who is it for

Electricians, panel builders, and maintenance technicians who need a dependable DIN rail-mounted breaker for distribution boards and control panels. Ideal for protecting cables and equipment in industrial and building automation systems.
