2CSF204001R1400: F204AC-40/0.03 RCCB: residual-current protection and upstream coordination
The ABB F204AC-40/0.03 is a four-pole residual current circuit breaker with a 40 A rated current and 30 mA residual-current threshold. ABB describes it as a Type AC F200 device. It provides residual-current protection and does not replace the required overcurrent protection, which must be coordinated separately.

The table summarizes family or catalog values for identification and initial selection. Confirm the nameplate, environmental limits, standards, revision and options for the exact device before procurement or engineering approval.
Application and system selection
Select an RCCB after reviewing the earthing system, expected leakage currents, load waveform and required sensitivity. Type AC is intended for sinusoidal residual currents; applications with electronic converters may require another residual-current type under applicable standards. Confirm whether 30 mA additional protection is required and whether nuisance-trip risks are controlled.
Configuration and compatibility
Check the complete F204 code, pole count, current rating, type, voltage and upstream short-circuit protection. Confirm the manufacturer’s conditional short-circuit rating with the selected backup device. The 40 A rating is not a statement that every downstream circuit can be protected at 40 A without additional coordination.

Installation and commissioning
Install with correct line/neutral routing through the sensing device and maintain separation from protective earth. Test the device using the manufacturer’s test control and an approved instrument at commissioning and at the prescribed maintenance interval. Verify selectivity with upstream RCDs and document the associated overcurrent protective device.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation 2CSF204001R1400, the order code where applicable, serial or hardware revision, quantity, operating environment, connected equipment and required delivery date. Include a legible nameplate image and relevant wiring, loop or switchgear drawing so the exact interface and configuration can be checked.
Ask the supplier to confirm accessories, revision compatibility and any approved successor in writing. Do not select solely from a family name or product photograph. Follow the current ABB installation and safety instructions for the exact unit.
