Overcurrent breaker S 301N 1P+N B 16 6000 A series DX3 407475

Reliable protection for your electrical installation

The S 301N 1P+N B 16 circuit breaker is a member of the DX3 series, designed to protect electrical circuits against overloads and short circuits. It is a critical component in every safe and efficiently operating electrical system—whether in residential or commercial buildings. This single-pole plus neutral (1P+N) breaker with a rated current of 16A provides effective protection, and its compact size (1 module width) simplifies installation in distribution boards.

Functionality and safety in one device

The S 301N breaker features a Type B characteristic, making it ideal for protecting circuits with inductive loads featuring moderate inrush currents. It performs excellently in safeguarding lighting circuits, power sockets, and household appliances. The rated short-circuit breaking capacity of 6kA (per EN 60898) and 10kA (per IEC 60947-2) ensures rapid and safe response during fault conditions. Additionally, the rated insulation voltage Ui is 250V, and the rated impulse withstand voltage Uimp is 4kV, guaranteeing a high level of operational safety.

Installation and compatibility

Installation of the breaker is simple and intuitive—it is designed for mounting on a DIN TH35 rail. It accepts single-core conductors from 0.75 mm² to 16 mm² and multi-core conductors from 0.75 mm² to 10 mm², offering great flexibility when connecting various cable types. The breaker has an IP20 protection rating, providing protection against finger contact, and operates reliably in temperatures ranging from -25°C to +70°C. Support for flush mounting and additional accessories enhances its versatility. Compliance with EN 60898 and IEC 60947-2 standards confirms its high quality and safety.
