Overcurrent breaker S 301 1P B 32 A 6000 A DX3 series 407435

Reliable protection for electrical installations – Legrand DX3 circuit breaker

This single-pole DX3 series circuit breaker is a key component of every safe and efficient electrical installation. Designed for both residential and commercial use, it provides effective protection against overloads and short circuits. Renowned for high reliability and easy installation, it is an ideal choice for professional electricians and demanding users.

The S 301 1P B 32 A breaker from the DX3 series is designed to protect circuits with a rated current of 32 A. Its B characteristic ensures rapid response to overloads while allowing brief current surges, such as those occurring during motor startup. The rated short-circuit breaking capacity of 6 kA (at 230 V) guarantees safety in the event of severe network disturbances.

Design and functionality

This breaker is engineered for convenient installation and operation. Its compact dimensions (1 module width) enable efficient use of space in distribution boards. The option for flush mounting increases installation flexibility. Additionally, high-quality materials ensure long-term, fault-free operation. The terminal accepts single-core conductors up to 35 mm² and multi-core conductors up to 25 mm², offering great flexibility in cable selection.

The use of B characteristic makes this breaker particularly suitable for protecting circuits with high inrush current loads—such as electric motors or transformers. This ensures not only safety but also minimizes the risk of unnecessary tripping during normal device operation. The breaker complies with safety standards (EN 60898 and IEC 60947-2), confirming its high quality and reliability. It operates in a temperature range from -25°C to 70°C, making it suitable for use in diverse environmental conditions.
