Residual Current Circuit Breaker 2P Legrand P302 40A 30mA Type AC (411510)
The Legrand P302 residual current circuit breaker 2P 40A 30mA Type AC is a DIN-rail mountable safety device that monitors alternating residual currents and disconnects the protected circuit when leakage exceeds the set sensitivity. Designed for residential and light commercial electrical installations, this 2-pole RCD provides personnel and equipment protection against electric shock and insulation faults while integrating into standard distribution boards.
The device combines a compact two-pole design with reliable residual current detection specific to AC-type leakage. With a 40 A rated current and 30 mA tripping sensitivity, it balances continuity of service with effective protection against dangerous touch voltages. DIN-rail mounting and compatibility with common distribution boards simplify installation and maintenance. The mechanical construction ensures clear manual operation and visible trip indication for quick status checks.
Install the RCD on a standard DIN rail inside the distribution board, ensuring correct phase and neutral connections according to local wiring regulations. Tighten terminal screws to the manufacturer's recommended torque and verify that the protective earth is present in the installation. After wiring, perform the built-in test function by pressing the test button to confirm correct operation and tripping. Regularly check the device visually and operate the test button periodically to ensure ongoing functionality.
Place the RCD on the incoming side of the circuit it is intended to protect and combine it with appropriately rated overcurrent protection upstream or downstream as required. For circuits supplying appliances with electronic components, verify compatibility with AC-type detection; consider a different residual current type if pulsating DC or smooth DC leakage is expected. Adhere to local electrical codes and engage a qualified electrician for installation and testing.
