Circuit breaker S 303 3P C 32A 6000A TX3 403548

Overcurrent circuit breaker S 303 TX³ is a reliable protection for electrical installations against the effects of overloads and short circuits. This model, with a rated current of 32A and C characteristic, is perfect for both home and commercial installations. The three-pole design provides comprehensive circuit protection.

Protection and functionality

The S 303 circuit breaker is designed with safety and ease of use in mind. The C characteristic means that the breaker 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 will prevent unnecessary tripping of the circuit. The rated short-circuit breaking capacity of 6kA at 400V and 10kA at 230V guarantees effective protection against serious failures. Energy limitation class 3 confirms its high effectiveness in suppressing arc fault energy.

Installation and compatibility

The circuit breaker is easy and intuitive to install thanks to the possibility of mounting on a TH35 rail. Compact dimensions – only 3 modules wide – allow for efficient use of space in the distribution board. The circuit breaker is compatible with a wide range of DX³ series accessories, such as auxiliary contacts, undervoltage releases or remote drives, allowing it to be adapted to individual installation needs. Additionally, the possibility of connection using comb or pin busbars increases installation flexibility.

Technical specifications and application

The S 303 TX³ circuit breaker meets the standards EN 60898-1 and EN 60947-2, which guarantees its compliance with applicable regulations and safety standards. The degree of protection IP20 provides protection against accidental contact. Rated voltage 400V and insulation voltage 500V ensure safe operation in typical electrical installations. A wide frequency range (50-60 Hz) allows its use in various power systems. Halogen-free construction increases safety in the event of a fire.
