## Summary description

Legrand P312 is a 2-pole residual-current circuit breaker with overcurrent protection rated 10 A, B characteristic, and 30 mA residual current sensitivity (type AC). Designed to combine short-circuit/overload protection and earth-leakage detection in one device, it is used for protecting circuits and people in domestic and light-commercial installations. Mounts on DIN rail for standard electrical panels.

## Long description

Legrand P312 is a compact 2-pole residual-current circuit breaker with integrated overcurrent protection rated for 10 A, B characteristic, and 30 mA residual current sensitivity (type AC). It combines short-circuit and overload protection with earth-leakage detection in a single DIN-rail mounted device intended for domestic and light-commercial electrical installations. The device is designed to protect wiring, connected equipment and persons from fault currents while fitting standard distribution boards.
Advantages
This residual-current circuit breaker provides combined functions of a miniature circuit breaker and an RCD, reducing component count and saving space in the panel. The B characteristic ensures fast tripping on moderate to high short-circuit currents while the 30 mA residual current sensitivity offers protection against dangerous earth-leakage faults. The 2-pole construction allows simultaneous isolation of phase and neutral in single-phase circuits. Its DIN-rail mounting and standardized width make installation straightforward during new builds or retrofits.
Suitable for
Protection of single-phase circuits in homes and apartments
Small commercial and light-industrial distribution panels
Final circuits feeding sockets, lighting and small appliances
Circuit upgrade where combined overcurrent and earth-leakage protection is required
Key specifications
Poles: 2-pole device for phase and neutral switching
Rated current: 10 A
Tripping characteristic: B-type overcurrent curve
Residual current sensitivity: 30 mA, AC type (sensitive to sinusoidal alternating leakage)
Functions: combined overcurrent protection and earth-leakage detection
Mounting: DIN-rail compatible for standard distribution boards
Application: intended for domestic and light-commercial circuits
How to use
Install the device on a standard DIN rail inside the distribution board following applicable electrical regulations and safety procedures. Connect the incoming supply to the designated line terminal and the load conductors to the load terminals, ensuring correct phase and neutral wiring. After wiring, switch the device on to restore the circuit and test the residual-current function by using a suitable test button on the unit or an external RCD tester to confirm trip at the rated residual current. Routine inspection and periodic testing are advised to maintain protective performance.
Usage recommendations
Use this breaker on circuits where protection against earth-leakage and overcurrent is required simultaneously. Verify compatibility with the circuit’s expected load and upstream protection, and follow local electrical codes for installation and periodic testing. For circuits with non-sinusoidal leakage currents or sensitive electronic loads, consider devices rated for pulsating DC or type A detection where appropriate.
