Residual Current Breaker with Overcurrent Protection P314 4P C 16A 30mA TYPE AC DX3 411186

Multifunctional electrical installation protection

The P314 4P C 16A 30mA type AC differential-overcurrent circuit breaker from the DX³ series is a comprehensive solution providing protection against short circuits, overloads, and electric shock. The device combines the functions of an overcurrent and residual current circuit breaker, allowing for effective protection of electrical circuits in residential and commercial buildings. Integrating these two functions into one device optimizes space utilization in the distribution board.

Design and application

The P314 circuit breaker is designed for mounting on a TH35 rail. Its four-pole design provides full protection in three-phase and single-phase circuits with a neutral conductor. Characteristic C allows for safe starting of devices with motors that generate high inrush currents – the circuit breaker reacts more slowly to short-term current surges, avoiding unnecessary tripping. The use of type AC means that the device effectively detects sinusoidal leakage currents, providing protection against electric shock.

Key features and benefits

• Versatile protection: Protects against overloads, short circuits and electric shock.

• Compact design: Integration of two functions in one device saves space in the distribution board.

• Easy diagnostics: Equipped with a test button to check the correct operation of the circuit breaker.

• High breaking capacity: Rated short-circuit breaking capacity up to 6 kA (according to EN 61009-1) ensures effective protection of the installation in the event of a short circuit.

• Compatibility: Works with the HX³ Energy Optimal Distribution System up to 125 A and a wide range of accessories (auxiliary contacts, release units).

• Safety: Has a lock preventing accidental switching on of the circuit breaker after it has been switched off.

• Durable construction: Made of high-quality materials, ensuring reliable operation for a long time.

Additional information: IP20 protection degree, limitation energy class 3, impulse withstand voltage 0.25 kA and compliance with EN 61009-1 and IEC 60947-2 standards guarantee the safety and reliability of the device. At the same time, the disconnectable N pole increases the functionality and safety of the electrical installation.
