Schneider RCCB 25A 4P A9R50425 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 features a 25A current and a 30mA leakage sensitivity. When comparing, distinguish between the current flowing through the device and the leakage value that triggers disconnection, and review the appropriate protection type for your loads.
Practical Benefits
- Adds earth leakage detection functionality to the protection system when selected and installed correctly.
- The presence of a specific rated current and leakage sensitivity allows for clear comparison of the device with distribution board requirements.
- Distinguishing between protection type and current helps avoid confusion between wiring protection and leakage protection.

Who Needs This Product?
Technicians who assemble and maintain distribution boards in buildings, 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 Qualified Technicians
The following steps outline the general workflow. Refer to the manufacturer's diagram for reference A9R50425 to identify terminals and connection values. Do not perform work on a circuit connected to a power supply.
- The technician disconnects all power sources, secures them against reactivation, and verifies the absence of voltage with an appropriate tool.
- Matches the device reference, number of poles, current, and voltage with the board diagram, and reviews conductor cross-sections and protection coordination.
- Installs the component on the rail or its designated position after ensuring compatibility, and identifies the supply and output from the manufacturer's diagram for this reference.
- Performs connections with the torque, stripping length, and wire gauges specified in the model manual; do not carry these values over from a similar device.
- Checks the tightness of the installation and connections, then closes the covers and performs the required functional and protection tests before handing over the circuit.
Frequently Asked Questions Before Purchasing
Does an RCCB protect against overload and short circuits?
An RCCB does not include overcurrent protection, therefore it requires coordination with a suitable circuit breaker or fuse. It should not be used as a substitute for an overload and short-circuit breaker.
Does 40A mean the leakage sensitivity is 40A?
No. The rated current and leakage sensitivity are two different values; sensitivity here is indicated in milliamperes (mA), while the rated current concerns the current flow through the device.
Is the AC type suitable for all electronic loads?
Not automatically. The technician determines the required protection type based on the shape of the potential leakage current and the nature of the loads; some circuits may require a different type.
