SZ203-C10 overcurrent circuit breaker, 3P, C characteristic, 10A, 6kA, AC 2CDS253025R0104

3P Circuit Breaker – reliable protection for electrical installations

This three-pole circuit breaker from the S203-C10 series by ABB is a key element of every safe and reliable electrical installation. Designed to protect against overloads and short circuits, it provides effective protection for wires and electrical devices in residential, commercial and industrial buildings. Characteristic C makes it particularly recommended for circuits with devices generating surge currents, such as motors or transformers.

This circuit breaker is characterized by a high short-circuit breaking capacity of 6kA at 400V, which guarantees a quick response in the event of a failure. Mounting on a DIN rail TH35-7.5 or TH35-15 is simple and intuitive, and the compact dimensions (width of 3 modules) allow for optimal use of space in the switchgear cabinet. The rated current of 10A makes it suitable for protecting circuits with medium loads.

Solid construction and compliance with standards

The circuit breaker is made of high-quality insulating material (group I, RAL 7035), which ensures durability and resistance to mechanical damage. It meets the requirements of energy limitation category 3 and surge voltage category 3, which confirms its effectiveness in protecting installations from the effects of voltage disturbances. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4kV, which ensures safety even in difficult operating conditions. Protection degree IP20 protects against accidental contact.

Versatile application and easy installation

This ABB circuit breaker is not only a protective element, but also a convenient solution for installers. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) and from 0.75 mm² to 25 mm² (stranded) provides flexibility during installation. Thanks to the wide range of operating temperatures (-25°C to +55°C), it can be used in various environmental conditions. Additionally, the possibility of mounting in any position makes it easy to adapt to specific installation needs.
