Overcurrent circuit breaker, 4P, C characteristic, 20A, 6kA, AC | S204-C20 2CDS254001R0204

Reliable protection of electrical installations – ABB S204-C20 circuit breaker

This four-pole circuit breaker with C characteristic is a key element of every safe and reliable electrical installation. Designed by the renowned company ABB, the S204-C20 model provides effective protection against overloads and short circuits, guaranteeing safety and longer life of connected devices. It is an ideal solution for both home, commercial and industrial installations.

Functionality and technical parameters

The S204-C20 circuit breaker is characterized by a rated current of 20A and a short-circuit breaking capacity of up to 6kA at AC voltage. The C characteristic provides a delayed tripping time, which is particularly important for loads with high inrush current, such as motors or transformers. DIN rail mounting simplifies and speeds up installation, and the compact dimensions (4 modules wide) allow for efficient use of space in the distribution board. The rated impulse withstand voltage of 4kV increases resistance to sudden voltage surges.

• A wide range of operating temperatures allows installation in various conditions – from -25°C to +55°C.
• Compliance with IEC EN 60898 and IEC EN 60947-2 standards ensures high safety and reliability standards.
• Flexibility in cable selection thanks to the possibility of connecting solid conductors with a cross-section of 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm².
• Overvoltage category III guarantees protection in installations exposed to medium levels of overvoltage.
• Protection class IP20 protects against touching with fingers and solid objects larger than 12.5 mm, providing additional safety.

Application and benefits

The S204-C20 circuit breaker is used in lighting circuits, electrical outlets, as well as in protecting electrical devices with significant power consumption during start-up. Its versatility makes it an excellent choice for both professional installers and end-users looking for reliable protection of their electrical installation. By choosing this circuit breaker, you are investing in safety, durability and peace of mind.
