Residual current circuit breaker P 314 4P C 10 A 30 mA Type A, DX3 series 411233

Protection and Safety in One Device

The residual current circuit breaker P 314 4P C 10 A 30 mA Type A from the DX3 series is a comprehensive solution ensuring protection of electrical installations and users. It combines the functions of an overcurrent and residual current device, safeguarding against the effects of overloads, short circuits, and electric shocks. This is an ideal solution for both installers and end-users seeking reliable protection.

Functionality and Design

This four-pole (4P) circuit breaker with a rated current of 10 A and characteristic C provides optimal protection for electrical circuits. The C characteristic allows for short-term overloads, which is particularly important when starting motor-driven equipment—preventing unnecessary tripping. The rated residual current of 30 mA ensures rapid response upon detection of earth leakage, minimizing the risk of electric shock. Equipped with a lockout mechanism, it prevents accidental re-energization after tripping due to a fault.

Application and Compatibility

The P 314 DX3 breaker is designed for use in AC installations with a rated voltage of 400 V and frequency of 50 Hz. Its width of 4 modules enables efficient space utilization in distribution boards. Additionally, it features a simultaneously disconnected neutral pole, enhancing its functionality. The rated short-circuit breaking capacity (Icn) reaches up to 6 kA, while the switching capacity reaches 10 kA, in accordance with IEC 60947-2, ensuring effective protection even during severe faults. The device complies with EN 61009-1 requirements and has a short-circuit breaking capacity of up to 6 kA.
