## Summary description

Schneider Electric residual current circuit breaker (RCD) 2-pole, 40 A rated current, 30 mA residual sensitivity, Type AC (A9Z11240). Provides protection against earth leakage and reduces risk of electric shock by detecting AC leakage currents. Suitable for residential and light commercial electrical installations, distribution boards and branch circuit protection.

## Long description

Schneider Electric residual current circuit breaker 2P 40A 30mA Type AC provides earth-leakage protection for single-phase distribution circuits. The two-pole RCD monitors current balance between live and neutral conductors and trips when an alternating leakage current exceeds 30 mA. Designed for residential and light commercial electrical installations, this device helps reduce the risk of electric shock and provides an additional layer of protection alongside overcurrent devices in distribution boards and branch circuits.
Advantages
The device offers reliable sensitivity to alternating residual currents with a 30 mA trip threshold, enabling early disconnection in the event of faults. Its two-pole construction allows simultaneous isolation of live and neutral, simplifying installation in single-phase circuits. Built to integrate into standard DIN-rail distribution boards, the unit is compact and suitable for retrofit or new installations where space and clear fault indication are required.
Suitable for
Residential main and sub-distribution boards
Light commercial premises and small offices
Protection of branch circuits supplying sockets, lighting, and household appliances
Areas requiring person-protection against electric shock
Key specifications
Poles: 2 (two-pole device for live and neutral)
Rated current: 40 A
Residual operating current (sensitivity): 30 mA
Tripping characteristic: Type AC — detects AC sinusoidal leakage currents
Mounting: DIN-rail compatible form factor for standard distribution boards
Intended use: Protection against earth-leakage and electric shock in single-phase circuits
How to use
Install the RCD on a standard 35 mm DIN rail inside the distribution board and connect the incoming live and neutral conductors to the designated terminals, observing correct polarity and tightening torques recommended by the panel manufacturer. Connect outgoing circuits to the load terminals. After wiring, perform insulation and polarity checks, then test the device using its built-in test button to confirm operation. Incorporate the RCD as part of a coordinated protection scheme together with appropriate overcurrent protection devices.
Usage recommendations
Regularly test the device using the test button at least once every three months and after any maintenance work. Ensure upstream overcurrent protection is correctly rated and coordination between devices is verified by a qualified electrician. Replace the RCD if it fails to trip during testing or shows signs of mechanical damage.
