Overcurrent circuit breaker, 1P+N, C characteristic, 4A, 6kA, AC | S201-C4NA 2CDS251103R0044

Reliable protection for your electrical installation

This single-pole circuit breaker with an additional neutral pole is a compact and effective solution for protecting electrical circuits in residential and commercial buildings. Designed by ABB, the S201-C4NA model combines high reliability with ease of installation, ensuring safety and user comfort. It is characterized by a rated current of 4A and a short-circuit breaking capacity of up to 6kA, which guarantees a quick response in the event of overloads and short circuits.

Functionality and technical parameters

This circuit breaker has a C characteristic, which means it is ideal for circuits with devices generating inrush currents during start-up – such as motors or transformers. This prevents unnecessary tripping during short-term current surges, while still providing effective protection against overloads. The rated impulse withstand voltage of 4kV and the high surge category (III) increase resistance to network disturbances. The ability to connect wires with a cross-section from 0.75 mm² to 25 mm² provides flexibility when selecting wires.

• Protects the circuit from damage caused by excessive load or short circuit.
• C characteristic provides a delayed response to short-term current surges – ideal for devices with motors.
• Short-circuit breaking capacity of 6kA guarantees a quick and effective response in the event of a short circuit.
• Two-pole design (1P+N) provides additional safety by disconnecting the neutral pole.
• Width of 2 modules facilitates mounting in electrical distribution boards thanks to its compact dimensions.
• Wide operating temperature range (-25°C to +55°C) allows use in various environmental conditions.
• Protection degree IP20 protects against touching with fingers and solid objects with a diameter greater than 12.5 mm.

Installation and compliance with standards

The S201-C4NA circuit breaker is designed for mounting on a TH35 rail (standard mounting rail). It meets the requirements of EN 60898 and IEC 60947-2 standards, which confirms its safety and reliability. The energy limitation class is 3, which means it is suitable for use in installations with medium impact energy. Adapted to operate in networks with a frequency of 50-60Hz and a rated voltage of 230V AC.
