Overcurrent circuit breaker, 3P, C characteristic, 32A, 10kA, AC | S203M-C32 2CDS273001R0324

Electrical installation protection with ABB S203M-C32 circuit breaker

This three-pole circuit breaker with C characteristic is a reliable solution for protecting electrical circuits in residential and commercial buildings. It provides effective protection against overloads and short circuits, minimizing the risk of damage to installations and equipment. Its compact size – only 3 modules wide – makes it easy to install even in crowded distribution boards.

The S203M-C32 circuit breaker is designed to operate in networks with a voltage of 400V, and its rated current of 32A makes it ideal for protecting circuits with medium loads. The C characteristic provides a delayed tripping response to short-term overloads, which is particularly important for devices with induction motors or other elements generating high starting currents. This avoids unnecessary tripping of the circuit during normal operation.

Application and design features

This circuit breaker is used in a wide range of electrical installations, from home distribution boards to commercial facilities. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation. The ability to work with wires with a cross-section from 0.75 mm² to 35 mm² (solid) and 0.75 mm² to 25 mm² (stranded) provides great flexibility when selecting power cables. The IP20 degree of protection prevents finger contact, increasing safety.

• High short-circuit breaking capacity: 10kA at 400V and 230V and up to 15kA/25kA according to IEC 60947-2, ensuring effective protection in the event of a short circuit.
• Wide operating temperature range: from -25°C to +55°C, allows the circuit breaker to be used in various environmental conditions.
• Expandability: compatibility with additional accessories allows you to adapt the functionality of the circuit breaker to individual installation needs.
• Energy limitation class 3: provides adequate protection in the event of an electric arc.
• Surge category III: resistance to overvoltages occurring in electrical installations.
• Power loss at 11.1W: affects the energy efficiency of the installation.

This circuit breaker is not only a protective element, but also an investment in the safety and reliability of your electrical installation – for both professional installers and end users.
