Schneider RCCB 63A 4P EZ9R36463 is a choice 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 63A 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 residual current 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 between the device and panel requirements.
- Distinguishing between protection types and current helps avoid confusion between wiring protection and leakage protection.

Who Needs This Product?
Technicians involved in the assembly and maintenance of building distribution boards, whenever earth leakage protection is required according to the protection scheme. The type, sensitivity, current, and number of poles must be selected in coordination with the other circuit breakers and loads.
Installation and Verification Procedure — For Authorized Technicians
The following steps outline the general workflow; refer to the manufacturer’s diagram for the EZ9R36463 reference to determine terminals and connection values. Work must not be performed 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.
- Installs 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 using the torque, stripping length, and wire gauges specified in the model manual; these values should not be taken from a similar device.
- Checks the integrity of mounting and connections, closes covers, and performs the required operational and protection tests before commissioning the circuit.
Frequently Asked Questions Before Buying
Does an RCCB protect against overload and short circuits?
An RCCB does not include overcurrent protection, so 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 expressed 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 type of protection based on the expected leakage current waveform and the nature of the loads; some circuits may require a different type.
