Residual Current Circuit Breaker (RCCB) P312 2P C 10A 30mA TYPE AC DX3 411011

### Protection and reliability in your electrical installation

This two-pole RCBO P312 DX³ from Legrand is a key element ensuring safety and protection in every electrical circuit. It combines the functions of an overcurrent circuit breaker and a residual current device, offering comprehensive protection against the effects of overloads, short circuits and electric shock. This is an ideal solution for both professional installers and demanding end users.

Functionality and construction

The P312 circuit breaker is characterized by a compact design, taking up only 2 modules on a TH35 rail. Its C characteristic provides delayed tripping with short-term overloads, which is particularly important when connecting devices with motors or other elements generating high starting current – it will not cause unnecessary disconnection of the circuit. The rated differential current of 30mA provides effective protection against electric shock, and the AC type guarantees proper operation in typical installations. Additionally, the presence of a test button allows for regular checking of the circuit breaker's functionality.

Key features and benefits

• Comprehensive protection: Protects against overloads, short circuits and electric shock in one device.
• C characteristic: Allows for trouble-free starting of devices with high starting current, minimizing the risk of false tripping.
• High breaking capacity: Rated breaking capacity of 6kA provides effective protection even in the event of serious short circuits.
• Compact dimensions: Occupies only 2 modules on a TH35 rail, saving valuable space in the distribution board.
• Easy installation and testing: Mounting on a TH35 rail and the presence of a test button facilitate installation and regular functional checks.
• Compliance with standards: Meets the requirements of EN 61009-1 and IEC 60947-2 standards, guaranteeing safety and reliability.
• Locking: Provides additional safety when working with the electrical installation.
• Versatility: Suitable for solid (0.75-16 mm²) and stranded (0.75-10 mm²) conductors.

Application

The P312 DX³ circuit breaker finds application in a wide range of electrical installations:

• Home installations: Protection of lighting, socket and household appliance circuits.
• Commercial installations: Protection of circuits in offices, shops and other public utility facilities.
• Industrial installations: Protection of circuits powering machines and production equipment (taking into account the C characteristic).
• New installations: An ideal choice when building new electrical installations, ensuring a high level of safety from the very beginning.
• Modernization of existing installations: Possibility of replacing older circuit breakers with a more modern and safe solution.
