Residual current circuit breaker P 314 4P C 32 A 300 mA type AC, DX3 series 411208

Protection and reliability in one device

This four-pole residual current circuit breaker P 314 from the DX³ series by Legrand is a comprehensive solution ensuring the safety of electrical installations. It combines the functions of an overcurrent and residual current device, protecting against the effects of overloads, short circuits, and electric shocks. It is an ideal choice for both professionals and end-users who value reliability and ease of use.

Functionality and installation

The P 314 breaker, rated at 32A and with a sensitivity of 300mA (Type AC), performs excellently in protecting electrical circuits in residential and commercial buildings. The C characteristic ensures delayed tripping during brief overloads, which is particularly important when operating equipment with electric motors or other components generating high inrush currents. Installation is simple and intuitive thanks to its modular design—the device occupies 4 modules on a TH35 rail. Additionally, the lockout feature prevents accidental re-energizing after the breaker has tripped.

Safety and compliance with standards

The P 314 residual current circuit breaker meets rigorous safety standards, providing effective protection for people and property. Its rated short-circuit breaking capacity reaches up to 6 kA (per EN 61009-1) or 10 kA (per IEC 60947-2), ensuring reliable operation even during severe electrical network disturbances. The IP20 protection rating prevents accidental contact with live parts. The device also features a test button for regular functional verification. The rated residual current of 0.3 A effectively detects earth leakage currents, minimizing the risk of electric shock.
