## Summary description

Schneider Electric residual current circuit breaker A9Z11440 is a 4-pole device rated 40 A with 30 mA residual current sensitivity. Designed for AC and iID detection, it provides protection against earth leakage and reduces risk of electric shock. Suitable for residential and light-commercial installations to protect circuits, appliances and personnel.

## Long description

Schneider Electric A9Z11440 residual current circuit breaker is a 4-pole device with 40 A nominal current and 30 mA residual current sensitivity for AC and iID detection. It is designed to interrupt supply quickly when it detects leakage to earth, helping to reduce the risk of electric shock and limit fire risk caused by insulation faults. The compact modular design fits standard distribution boards and is suitable for residential and light-commercial installations where multi-pole isolation and earth-leakage protection are required.
Advantages
The device provides selective residual current detection for AC and pulsed DC (iID), combining reliable leakage detection with coordinated tripping characteristics. Four-pole switching ensures simultaneous disconnection of all phases and neutral, improving safety on three-phase circuits. Rated at 40 A with 30 mA sensitivity, it balances protection for people with continuity of service for connected equipment. The breaker’s modular format and standard mounting make installation and replacement straightforward for electricians.
Suitable for
Protection of three-phase circuits in residential or light-commercial distribution boards
Electrical circuits supplying motors, heating systems or distribution feeders
Areas where personnel protection against earth-leakage is required (bathrooms, kitchens, utility rooms)
Applications requiring coordinated detection of AC and pulsed DC leakage currents
Key specifications
Number of poles: 4
Rated current: 40 A
Residual current sensitivity: 30 mA
Detection type: AC and pulsed DC (iID)
Function: Residual current detection and circuit breaking
Mounting: DIN-rail compatible modular housing
Typical applications: Residential and light-commercial circuits
How to use
Install the breaker in a standard distribution board on a DIN rail and connect line and neutral conductors according to the wiring diagram and local electrical regulations. Ensure the device is mounted in a dry, accessible location with adequate clearances for wiring and terminal access. After installation, test the residual current function using an appropriate testing procedure or test instrument to confirm correct operation and coordinated tripping before placing the circuit into regular service.
Usage recommendations
For reliable protection, combine this residual current breaker with properly rated overcurrent protection and adhere to local wiring rules. Periodically test the residual current function and inspect connections for tightness and signs of overheating. Replace the device if it fails testing or shows visible damage.
