Circuit breaker S 303 3P C 50A 6000A TX3 403550

Safety and reliability in your electrical installation

The S 303 TX³ circuit breaker is a key element in protecting electrical installations from the effects of overloads and short circuits. This three-pole circuit breaker with a rated current of 50A and C characteristic provides effective protection for electrical circuits in residential, commercial and industrial buildings. The breaking capacity of 6kA guarantees a quick response in the event of a failure, minimizing the risk of damage and fire.

Design and installation – simplicity for professionals and users

The S 303 TX³ circuit breaker has been designed for easy installation. Compact dimensions (3 module width) allow for efficient use of space in the distribution board. Installation is carried out on a standard TH35 rail, and the possibility of connection using comb or pin busbars increases installation flexibility. Terminal covers provide safety during wiring.

Characteristics and application – protection tailored to your needs

The C characteristic of the circuit breaker means that it reacts with a delay to short-term current surges, which is particularly important when connecting devices with electric motors or other loads with high inrush current. This avoids unnecessary tripping of the circuit breaker during normal operation of the devices. This circuit breaker is ideal for lighting, socket and power circuits for household appliances. The circuit breaker has a breaking capacity of 6 kA at 400 V AC and 10 kA at 230 V AC, which provides effective protection against the effects of short circuits. The rated voltage is 400 V AC, making it compatible with most standard electrical installations. The IP20 degree of protection protects against finger contact and solid objects larger than 12.5 mm. Expandability through compatibility with DX³ series accessories (auxiliary contacts, undervoltage and remote control releases) allows you to tailor functionality to individual needs. The mechanical durability of up to 20,000 switching cycles guarantees long-lasting and reliable operation. The circuit breaker operates in the frequency range of 50-60 Hz, ensuring versatility in various energy networks.
