Why Choose the ABB F204B+25/0.03 RCCB?
The ABB F204B+25/0.03 is a high-performance four-pole Type B+ residual current circuit breaker (RCCB) designed to provide residual-current protection in commercial and industrial electrical installations. As part of the ABB System pro M compact F200 B+ series, it detects sinusoidal AC, pulsating and smooth DC residual currents, making it particularly suitable for installations containing modern power electronic equipment.
The enhanced Type B+ characteristic extends residual-current detection over a frequency range of 0–20 kHz and is designed to provide enhanced preventative fire protection. ABB's F200 B+ devices are suitable for applications where frequency converters, drives and other electronic equipment can produce complex residual-current waveforms that require protection beyond conventional Type A RCCBs.
With a rated current of 25 A and a rated residual operating current of 30 mA, the F204B+25/0.03 provides additional protection against electric shock as well as residual-current protection for equipment and installations. Its four-pole configuration makes it suitable for three-phase systems with neutral, while its modular construction enables straightforward DIN-rail installation in distribution boards and electrical control panels.
Key Advantages
- Advanced Type B+ residual-current detection for AC, pulsating and smooth DC residual currents.
- 25 A rated current for commercial and industrial electrical circuits.
- 30 mA residual-current sensitivity providing additional protection against electric shock.
- Four-pole configuration suitable for three-phase systems with neutral.
- Extended 0–20 kHz residual-current detection frequency range.
- Enhanced preventative fire protection compared with standard Type B RCCBs.
- DIN-rail mounting for straightforward integration into distribution boards and control panels.
Key Features
- ABB System pro M compact F200 B+ series.
- Type B+ residual-current characteristic.
- 25 A rated current.
- 30 mA rated residual operating current (IΔn).
- Four poles (4P).
- Detection of sinusoidal AC, pulsating and smooth DC residual currents.
- 0–20 kHz frequency range for residual-current detection.
- 10 ms short-time delayed characteristic.
- 3 kA surge-current withstand capability.
- DIN-rail mounting for modular electrical distribution systems.
Enhanced Type B+ Residual-Current Protection
Type B+ RCCBs are intended for electrical installations where loads can generate residual currents with AC, pulsating DC, smooth DC and higher-frequency components. The ABB F204B+25/0.03 detects residual currents across an extended frequency range of up to 20 kHz, making it particularly useful for commercial and industrial installations containing electronic power conversion equipment.
The 30 mA sensitivity provides additional protection against electric shock, while the B+ characteristic offers enhanced preventative fire protection. As an RCCB, the F204B+25/0.03 provides residual-current protection but does not incorporate overcurrent protection, so suitable protection against overloads and short circuits should be provided separately as required by the installation design.
Typical Applications
- Industrial electrical distribution systems.
- Commercial and industrial installations requiring Type B+ protection.
- Frequency converter and variable speed drive installations.
- Industrial machinery and automation systems.
- Electrical systems containing power electronic equipment.
- Distribution boards and electrical control panels.
