Residual current circuit breaker P312 2P C 20A 30mA TYPE AC DX3 411014

Safety and reliability in your electrical installation

This two-pole residual current circuit breaker (RCCB) P312 DX³ from Legrand is a key element ensuring comprehensive protection in electrical circuits. It combines the functions of an overcurrent circuit breaker and an RCCB, protecting against the effects of overloads, short circuits and electric shock. This is an ideal solution for both professional installers and end-users who value safety and comfort.

Functionality and parameters tailored to your needs

The P312 circuit breaker is characterized by a rated current of 20A and a residual current of 30mA, providing effective protection in typical household and industrial applications. Characteristic C allows for trouble-free starting of devices with motors that generate short-term current surges. Type AC means that the circuit breaker reacts to alternating leakage currents, which is standard in most electrical installations. The breaking capacity of 6kA guarantees reliable operation in the event of a short circuit.

• Multi-level protection: Protects against overloads, short circuits and electric shock.
• Characteristic C: Allows starting of devices with motors without unnecessary tripping.
• Type AC: Standard protection against alternating leakage currents.
• Breaking capacity 6kA: Guarantees reliable operation in emergency situations.
• Two-pole: Provides full protection of the phase and neutral circuits.
• Mounting on TH35 rail: Quick and easy mounting in the distribution board.
• Locking: Additional protection against accidental switching on after switching off due to a fault.

Design and application

The DX³ series circuit breakers are distinguished by their compact design (width 2 modules) and high quality workmanship. They are designed for mounting on a TH35 rail, which facilitates their installation in electrical distribution boards. In addition, they have a test button allowing regular checking of the correct operation of the residual current device – this is a simple operation to ensure the continuous readiness of the device. These circuit breakers work with a wide range of conductors with a cross-section from 0.75 mm² to 16 mm², providing flexibility during installation. The degree of protection IP20 protects against finger contact and against the ingress of solid objects larger than 12.5 mm – sufficient for most standard indoor applications.
