Overcurrent breaker S 311 1P C 16 A 10000 A DX3 series 409114

DX³ Series Circuit Breakers – Reliable Protection for Electrical Installations

The DX³ series circuit breaker S 311 1P C 16 A is designed to protect electrical circuits against overloads and short circuits. It features a high breaking capacity, ensuring installation safety in the event of a fault. This universal device is suitable for both residential and industrial applications.

Construction and Operating Parameters

The circuit breaker is constructed from high-quality materials, ensuring durability and reliability. Its compact design (1 module width) facilitates easy installation in electrical distribution boards. The C characteristic provides delayed tripping during brief overloads, which is especially critical for devices with electric motors or other loads with high inrush currents. The rated current of 16 A makes it an ideal choice for protecting standard lighting and socket circuits.

Technical parameters enable precise selection for specific needs: high short-circuit breaking capacity (10 kA according to EN 60898 and 16 kA according to IEC 60947-2) ensures effective protection against short-circuit consequences. The rated voltage of 230 V makes it suitable for standard single-phase installations, while the C characteristic provides reliable protection against overloads and short circuits, minimizing unnecessary tripping during transient current surges. The device occupies only 1 module in the distribution board, saving space. It supports connection of single-core cables from 1.5 to 35 mm² and multi-core cables from 1.5 to 25 mm², offering flexibility in conductor selection. The wide operating temperature range (-25°C to +70°C) allows use in diverse environmental conditions.

Installation and Applications

Installation is simple and intuitive thanks to DIN rail TH35 mounting. The device is designed for flush mounting, ensuring a clean, aesthetic installation appearance. The S 311 breaker is suitable for protecting:

• Lighting circuits,
• Socket outlets,
• Electrical devices with power up to 3680 W (at 230 V),
• Electrical installations in residential, commercial, and industrial buildings.

In addition, DX³ series breakers are compatible with the HX³ Optimal Power Distribution System, enabling the creation of comprehensive and efficient power solutions. The option to add auxiliary components (auxiliary contacts, trip units) enhances device functionality and allows customization to meet individual user requirements.
