Overcurrent circuit breaker, 2P, C characteristic, 3A, 6kA, AC | S202-C3 2CDS252001R0034

Reliable protection of electrical installations with ABB S202-C3 circuit breaker

This two-pole overcurrent circuit breaker from ABB's Standard series is a key element of protection in any electrical installation. Designed to protect against overloads and short circuits, it ensures safe use and reliable operation. Characteristic C makes it ideal for circuits with devices generating surge currents, such as motors or transformers – it allows it to react more slowly to short current spikes, therefore tolerating the starting of such devices well. The rated short-circuit breaking capacity of 6kA at 400V guarantees effective disconnection of the circuit in the event of a failure.

Functionality and parameters for professionals

The S202-C3 circuit breaker is characterized by a wide range of permissible conductor cross-sections – from 0.75 mm² to 35 mm² for solid conductors and 0.75 mm² to 25 mm² for stranded conductors. Mounting on a DIN rail with a width of 2 modules facilitates installation and integration with existing infrastructure. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4kV, which ensures a high level of safety in various working conditions. The energy limitation class is 3, and the surge category is III, which confirms its suitability for demanding applications.

Universal application and compliance with standards

This circuit breaker is used both in domestic installations and in commercial and industrial facilities. Its compact dimensions (installation depth 69 mm) allow for installation even in limited space. It meets the requirements of EN 60898 and IEC 60947-2 standards, which guarantees its compliance with applicable regulations and safety standards. Designed to operate in ambient temperature from -25°C to +55°C, which makes it reliable even in difficult operating conditions. Power losses are only 2.6W, which translates to energy efficiency of the installation. Protection degree IP20 provides protection against accidental contact.
