Overcurrent breaker S 313 3P C 16 A 10000 A DX3 series 409254

Reliable Protection for Electrical Installations – Legrand DX³ Series Circuit Breaker

This three-pole circuit breaker from Legrand’s DX³ series, rated at 16A with characteristic C, is a critical component ensuring safety and reliability in any electrical installation. Designed for both residential and commercial applications, it effectively protects circuits against overloads and short circuits. Constructed from high-quality materials, it guarantees long-term, fault-free operation.

Functionality and Technical Specifications

The S 313 3P C 16A breaker features a high breaking capacity: up to 16kA at 400V and 32kA at 230V (compliant with IEC 60947-2). The C characteristic provides delayed tripping, which is essential for loads with high inrush currents such as motors or transformers. DIN rail mounting is simple and intuitive, while its compact size (3 modules wide) enables optimal space utilization in distribution boards. The breaker has an IP20 protection rating, safeguarding against accidental contact and dust ingress.

This breaker is ideal for protecting lighting and socket circuits thanks to its 16A rated current. The C characteristic ensures not only protection against overloads and short circuits but also enables smooth startup of motor-equipped devices. The high breaking capacity, reaching up to 32kA, guarantees effective protection during fault conditions. Installation is extremely straightforward thanks to its DIN rail-compatible design, saving time during setup. Its compact dimensions—just 3 modules wide—allow efficient use of space in distribution boards. The rated voltage of 400V ensures universal applicability across various electrical installations. The wide operating temperature range (-25°C to +70°C) enables reliable performance even in harsh environmental conditions.
