Overcurrent circuit breaker S 303 3P B 2 A 6000 A series TX3 403395

Protection of Electrical Installations with TX³ Series Circuit Breakers

The TX³ series S 303 circuit breaker is a reliable solution for protecting electrical installations against the effects of overloads and short circuits. This three-pole breaker with B characteristic and a rated current of 2A provides effective protection for circuits with a rated voltage of 400V. The rated short-circuit breaking capacity of 6kA at 400V and 10kA at 230V ensures rapid response during emergency situations, minimizing the risk of damage and fires.

Design and Installation

TX³ series breakers feature a well-thought-out design that simplifies both installation and subsequent wiring. The bottom clip and shielded terminals significantly streamline the installation process, saving time and improving work comfort. Compact dimensions—3 module widths and a mounting depth of 44 mm—allow efficient use of space in distribution boards. Flush-mounted installation further enhances the aesthetic appearance of the installation.

Application and Compliance with Standards

The S 303 TX³ breaker is suitable for a wide range of electrical installations, both in residential and commercial buildings. It complies with EN 60898 and EN 60947 standards, confirming its safety and reliability. Class 3 energy limitation and IP20 protection rating ensure adequate defense against environmental influences. The rated impulse withstand voltage of 4kV further increases the device’s resistance to sudden voltage fluctuations. The B characteristic ensures rapid response to current increases while remaining resistant to brief surges—critical when connecting devices with motors or other components generating inrush currents.
