Schneider RCCB 40A 2P A9R50240 is an option among residual current circuit breakers at Bashiti Stores, designed to detect residual current and disconnect the circuit when the specified leakage sensitivity is exceeded. This model has a 40-amp current rating and 30mA leakage sensitivity. When comparing, distinguish between the current passing through the device and the leakage value that triggers disconnection, and verify the appropriate protection type for the loads.
Practical Benefits
- Adds earth leakage detection functionality to the protection system when selected and installed correctly.
- The availability of a rated current and specific leakage sensitivity allows for clear comparison of the device with panel requirements.
- Distinguishing between protection type and current helps avoid confusion between wiring protection and leakage protection.

Who Needs This Product?
Distribution board assembly and maintenance technicians, when earth leakage protection is required according to the protection plan. The type, sensitivity, current, and number of poles must be selected in coordination with the rest of the breakers and loads.
Installation and Verification Method — For Professional Technicians
The following steps illustrate general workflow. Refer to the manufacturer's diagram for reference A9R50240 to determine terminals and torque values. Do not perform work on a circuit connected to power.
- The technician disconnects all power sources and secures them against accidental restart, then verifies the absence of voltage with a suitable tool.
- Matches the device reference, number of poles, current, and voltage with the panel diagram, and reviews conductor cross-sections and protection coordination.
- Mounts the unit on the rail or its designated position after ensuring compatibility, and identifies the supply and output from the manufacturer's diagram for this reference.
- Executes connections according to the tightening torque, stripping length, and wire cross-sections specified in the model manual; do not transpose these values from a similar device.
- Checks the integrity of mounting and connection, then closes the covers and performs the required operational and protection tests before handing over the circuit.
Frequently Asked Questions Before Buying
Does an RCCB protect against overload and short circuits?
The RCCB does not include overcurrent protection, therefore it requires coordination with a suitable breaker or fuse. It is not used as a substitute for an overload and short-circuit breaker.
Does 40 amps mean the leakage sensitivity is 40 amps?
No. Rated current and leakage sensitivity are two different values; sensitivity here is stated in milliamps, while the rated current concerns the current passing through the device.
Is the AC type suitable for all electronic loads?
Not automatically. The technician determines the required protection type based on the likely leakage current waveform and the nature of the loads; some circuits may require a different type.
