## Summary description

Legrand residual-current overcurrent protective device (RCCB + MCB) 2-pole, 20 A, B curve, 30 mA sensitivity, type AC P312. Combines earth-leakage protection with overcurrent/trip characteristic B for residential and light commercial circuits. Designed for protection against earth faults and short-circuits, suitable for distribution boards and appliance circuits.

## Long description

Legrand residual-current circuit breaker 2P 20A B 30mA type AC P312 combines residual-current (RCCB) and miniature circuit breaker (MCB) functions in a single device. It integrates earth-leakage detection with overcurrent and short-circuit protection, featuring a B curve trip characteristic and 30 mA residual current sensitivity. Intended for mounting in distribution boards, this compact two-pole unit protects circuits in homes and small commercial installations where selective protection against earth faults and overloads is required.
Advantages
This Legrand unit provides combined protection against residual currents and overcurrents in one module, reducing the number of devices in the panel and simplifying wiring. The 30 mA sensitivity meets common safety requirements for personal protection against electric shock, while the B curve ensures reliable operation for general-purpose circuits and lighting. The two-pole design isolates both live conductors simultaneously for safer maintenance and clearer fault identification.
Suitable for
Residential distribution boards and apartment electrical circuits
Small commercial or light-industrial installations with standard loads
Protection of lighting circuits, socket outlets, and household appliances
Circuit protection where earth-leakage detection and overcurrent trip are both required
Key specifications
Number of poles: 2 (double-pole isolation)
Rated current: 20 A
Tripping curve: B (suitable for general-purpose circuits)
Residual current sensitivity: 30 mA (type AC)
Type: combined residual-current device and overcurrent protection
Intended mounting: DIN rail in distribution boards
How to use
Install the device on a standard DIN rail inside the electrical distribution board according to local wiring regulations and the manufacturer's installation instructions. Connect the incoming and outgoing conductors to the marked terminals, ensuring correct polarity and secure tightening. Verify that the device rating (20 A, B curve, 30 mA type AC) matches the circuit requirements. After installation, test the residual-current trip using a test button if present or by an approved test procedure to confirm correct operation before energising end-user equipment.
Использование и обслуживание
If the device trips, identify and isolate the faulty load before resetting. Periodic testing of residual-current protection and visual inspection of terminal tightness are recommended to maintain reliable operation.
