Residual current circuit breaker P 314 4P C 25 A 300 mA type AC, DX3 series 411207

Comprehensive protection for your electrical installation

The differential circuit breaker P 314 4P C 25A 300mA from the DX³ series is a reliable device that combines the functions of an overcurrent and residual current breaker. It provides comprehensive protection of electrical circuits against the effects of overloads, short circuits, and electric shocks. This solution is ideal for both professional electricians and end-users who value safety and ease of use.

Design and application

This breaker is designed for DIN rail TH35 mounting in electrical distribution boards. Its compact dimensions—only 4 modules wide—allow efficient use of space within the distribution cabinet. The device is intended for protecting circuits with a rated voltage of 400V and a rated current of 25A. The C characteristic ensures delayed tripping during short-term overloads, which is particularly important when operating devices with electric motors or other loads with high inrush currents. The rated residual current of 300mA protects against dangerous earth leakage currents.

Safety and compliance with standards

The P 314 breaker complies with the requirements of IEC 60947-2 and EN 61009-1 standards, guaranteeing high quality and reliability. It features a short-circuit breaking capacity of up to 6kA (per EN 61009) or 10kA (per IEC 60947-2), ensuring effective protection of the installation in the event of a short circuit. Additionally, the built-in lock prevents accidental re-energizing after the breaker has tripped due to protection activation. The IP20 protection rating ensures protection against finger contact and access to live parts.

• Multifunctional: Combines overcurrent and residual current protection in a single device.
• Compact size: Occupies only 4 modules on TH35 rail, saving space in the distribution board.
• C characteristic: Resistant to short-term overloads, ideal for motor-driven equipment.
• High short-circuit breaking capacity: Effective protection against short-circuit consequences (up to 10kA).
• Standards compliant: Meets IEC 60947-2 and EN 61009-1 requirements, ensuring safety and reliability.
• Locking mechanism: Prevents accidental re-energizing after protection trip.
• Test button: Enables regular verification of the residual current device’s proper operation.
• Simultaneous neutral pole disconnection: Enhances safety during faults.

The P 314 breaker from the DX³ series is an investment in the safety of your electrical installation and peace of mind for you and your loved ones. It is a robust and reliable device that meets the expectations of even the most demanding users.
