Overcurrent circuit breaker, 1P+N, C characteristic, 20A, 6kA, AC | S201-C20NA 2CDS251103R0204

Reliable protection of electrical installations – ABB S201-C20NA circuit breaker

This single-pole plus neutral (1P+N) circuit breaker with characteristic C is a key element of every safe and efficient electrical installation. Designed by the renowned company ABB, it provides effective protection against overloads and short circuits in circuits with a rated current of 20A. This is an ideal solution for both installers and end-users who value safety and reliability.

Functionality and technical parameters

The S201-C20NA circuit breaker is distinguished by its compact design, taking up only 2 modules on a TH rail. Characteristic C means a delayed response to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high starting currents – this avoids unnecessary tripping of the circuit. The rated short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) guarantees a quick and safe response in the event of a failure.

• Wide range of applications: ideal for protecting lighting circuits, socket circuits and electrical appliances in residential, commercial and industrial buildings.
• Mounting: easy mounting on a TH rail – a standard solution in most switchboards.
• Conductor cross-sections: possibility of connecting solid conductors with a cross-section from 0.75 to 35 mm² and stranded conductors from 0.75 to 25 mm².
• Safety: meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, ensuring compliance with applicable safety regulations.
• Additional equipment: possibility of expanding with additional accessories increasing the functionality of the circuit breaker.

Construction and durability

The circuit breaker is made of high-quality materials, which guarantees its durability and reliability even in difficult working conditions (ambient temperature from -25°C to +55°C). The IP20 degree of protection provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm. Energy limitation class 3 indicates the ability to withstand impact energy without damage. The rated impulse withstand voltage of 4kV further increases safety.
