Overcurrent circuit breaker, 4P, C characteristic, 40A, 6kA, AC | S204-C40 2CDS254001R0404

Reliable protection of electrical installations – ABB S204-C40 circuit breaker

This four-pole circuit breaker from ABB with C characteristic is a key element ensuring safety in every electrical installation. Designed for both domestic and industrial applications, it effectively protects circuits against the effects of overloads and short circuits. Its solid construction and high breaking capacity guarantee reliable operation in critical situations.

Functionality and technical parameters

The S204-C40 circuit breaker stands out from the competition thanks to its versatility and high parameters. A rated current of 40A combined with a short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) makes it an ideal solution for a wide range of applications. The C characteristic provides delayed tripping, which is particularly important for pulsed loads such as motors or transformers – this avoids unnecessary tripping during device start-up. DIN rail mounting facilitates quick and easy installation.

• Modular width: 4 modules – compact dimensions allow for efficient use of space in the distribution board.
• Degree of protection IP20: Provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
• Wire cross-section: Accepts both solid (up to 35 mm²) and stranded (up to 25 mm²) wires – high flexibility when selecting power cables.
• Operating temperature: Wide operating temperature range from -25°C to +55°C – possibility of use in difficult environmental conditions.
• Compliance with standards: Meets the requirements of IEC EN 60898 and IEC EN 60947-2 standards, which confirms its safety and reliability.

Construction and application

The S204-C40 circuit breaker has been designed with durability and ease of use in mind. Its solid housing made of high-quality materials provides resistance to mechanical damage and external factors. Energy limitation class 3 guarantees minimization of the effects of short circuits on the environment. This makes the product perfect for both newly built and modernized installations. The possibility of mounting additional accessories expands the functionality of the circuit breaker, adapting it to the individual needs of the user. Designed to protect circuits with a rated voltage of 400V, as well as 230V AC, making it a versatile solution for various electrical installations.
