Schneider RCCB 40A 4P EZ9R36440 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 40A current rating and 30mA leakage sensitivity. When comparing, distinguish between the current passing through the device and the leakage value that triggers tripping, and verify the appropriate protection type for your loads.
Practical Benefits
- Adds residual current detection to the protection system when selected and installed correctly.
- Having a specific rated current and leakage sensitivity allows for clear comparison of the device against panel requirements.
- Distinguishing between the protection type and current helps avoid confusion between wiring protection and leakage protection.

Who needs this product?
Technicians preparing and maintaining distribution boards in buildings when a residual current protection function is required according to the protection plan. The type, sensitivity, current, and number of poles must be selected in coordination with the remaining circuit breakers and loads.
Installation and Verification Method — For Professional Technicians
The following steps outline the general workflow; the manufacturer's diagram for reference EZ9R36440 must be used to identify terminals and torque values. Do not perform work on a live circuit.
- The technician disconnects all power sources and secures them against accidental restart, then verifies the absence of voltage with an appropriate tool.
- Match the device reference, number of poles, current, and voltage with the panel diagram, and review conductor cross-section and protection coordination.
- Mount the unit on the rail or its designated position after ensuring compatibility, and identify the supply and output from the manufacturer's diagram for this reference.
- Execute connections with the torque, stripping length, and wire cross-sections specified in the model manual; do not transpose these values from a similar device.
- Check the tightness of the installation and connections, then close covers and perform required operational and protection tests before handing over the circuit.

FAQs Before Buying
Does an RCCB protect against overload and short circuits?
An RCCB does not include overcurrent protection, so it requires coordination with an appropriate circuit breaker or fuse. It is not used as a substitute for an overload and short-circuit breaker.
Does 40A mean the leakage sensitivity is 40A?
No. Rated current and leakage sensitivity are two different values; sensitivity here is indicated in milliamperes (mA), while the rated current refers to the current flow capacity of 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.
