- Vibration Resistance: Suitable for environments with mechanical vibration per IEC standards
- Test Button: Integrated monthly self-test function for compliance with IEC maintenance schedules
System Architecture & Signal Flow
The F204A-2 operates on a toroidal current transformer (CT) principle. Under normal conditions, the vectorial sum of currents through all 4 poles equals zero — no trip signal is generated. When a ground fault occurs, the imbalance current (IΔ) exceeds 30 mA, the CT output energizes the trip solenoid, and all 4 poles open simultaneously within the rated tripping time. The Type A detection circuit includes a half-wave rectifier stage to capture pulsating DC components generated by rectifier loads, ensuring reliable operation with modern electronic equipment.
Recommended upstream protection: ABB S200 series MCB or equivalent, rated ≥ 25 A with breaking capacity ≥ 6 kA. Downstream load: any 3-phase or single-phase loads not exceeding 25 A aggregate per phase.

Technical FAQ
Q: Can the F204A-2 protect circuits with VFD (Variable Frequency Drive) loads?
A: Yes. The Type A sensitivity rating covers pulsating DC residual currents generated by VFD rectifier stages. However, for drives with significant high-frequency leakage, consider ABB’s selective (Type S) or high-immunity variants to avoid nuisance tripping.
Q: Is the F204A-2 suitable for TN-S earthing systems?
A: Yes. The 4-pole configuration is compatible with TN-S, TT, and IT earthing systems. For TN-C systems, a 4-pole RCCB is not applicable — use a 2-pole unit on the phase conductors only.
Q: What is the difference between F204A-2 and F204AC-2?
A: The F204A-2 (Type A) detects AC and pulsating DC residual currents. The F204AC-2 (Type AC) detects AC residual currents only. Type A is the recommended choice for modern installations with electronic loads.
Q: Can this RCCB be used with ABB’s S200 MCB in a coordinated protection scheme?
A: Yes. The F204A-2 is designed to coordinate with ABB S200 series MCBs. The upstream MCB provides overcurrent and short-circuit protection; the RCCB provides residual current (ground fault) protection — a standard split-function protection arrangement.
Q: What maintenance is required?
A: IEC 61008-1 recommends monthly functional testing using the integrated TEST button. Annual inspection of terminal torque and visual check for mechanical damage is also recommended.
