Overcurrent circuit breaker, 3P, C characteristic, 20A, 6kA, AC | S203-C20 2CDS253001R0204

Overcurrent circuit breaker from the S200 series is a reliable protection for electrical installations against overloads and short circuits. Designed for use with AC circuits, it provides effective protection in both residential and commercial buildings. Characteristic C makes it ideal for circuits with high inrush current – it reacts more slowly to short current surges, therefore tolerates well the starting of devices with a motor.

This three-pole circuit breaker with a rated current of 20A and a short-circuit interrupting capacity of 6kA at 400V has been designed for durability and safety. DIN rail mounting is quick and easy, and a width of 3 modules allows for optimal use of space in the distribution board. The rated short-circuit interrupting capacity Icu reaches even 10kA at 400V and 20kA at 230V, providing confidence in emergency situations.

• Versatile application: ideal for protecting lighting, socket outlets and circuits with devices with high inrush current.
• High reliability: energy limitation class 3 and overvoltage category III guarantee stable operation even in difficult conditions.
• Easy installation: 3 module width facilitates installation and saves space in the distribution box.
• Wide operating temperature range: from -25°C to +55°C allows use in various environments.
• Expandability: compatible with additional equipment, increasing the functionality of the system.
• Safety confirmed by standards: meets the requirements of EN 60898 and IEC 60947-2 standards, ensuring compliance with applicable regulations.

The circuit breaker is characterized by a degree of protection IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. The cross-section of solid wires from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm² provides flexibility in the selection of supply wires. Power losses are only 7.5W, which translates to energy efficiency of the installation.
