Why Choose the ABB F204 B S-63/0.3 RCCB?
The ABB F204 B S-63/0.3 is a selective four-pole Type B residual current circuit breaker (RCCB) designed to protect electrical installations against residual currents to earth. Part of the established ABB F200 RCCB series, it provides all-current-sensitive protection for installations where sinusoidal AC, pulsating DC and smooth DC residual currents can occur.
This RCCB is particularly suitable for modern commercial and industrial electrical systems containing non-linear loads and power electronic equipment such as frequency converters. Its Type B characteristic provides detection of complex residual-current waveforms, while the selective S-type characteristic supports discrimination between upstream and downstream residual-current protection devices.
With a rated current of 63 A and a rated residual operating current of 300 mA, the F204 B S-63/0.3 is suitable for three-phase installations requiring selective residual-current and fire protection. The four-pole device operates at a rated voltage of 230/400 V AC and features a 5 kA surge-current withstand capability for increased resistance to unwanted tripping caused by transient currents.
Key Advantages
- Selective Type B residual-current protection for demanding electrical installations.
- 63 A rated current suitable for higher-current commercial and industrial circuits.
- 300 mA rated residual operating current suitable for earth-fault and fire protection applications.
- Four-pole configuration for three-phase systems with neutral.
- Detects sinusoidal AC, pulsating DC and smooth DC residual currents.
- Selective S-type characteristic supports coordinated residual-current protection.
- 5 kA surge-current withstand capability provides increased immunity to transient currents.

- Suitable for circuits where smooth DC residual currents can occur.
- DIN-rail mounting for modular electrical distribution systems.
Selective Type B Protection for Modern Electrical Systems
Type B RCCBs are designed for circuits where electronic equipment can generate residual-current waveforms that conventional Type AC or Type A devices may not fully detect. The ABB F204 B S-63/0.3 provides all-current-sensitive protection against sinusoidal AC, pulsating and smooth DC residual currents, making it particularly suitable for installations incorporating frequency converters and other power electronic equipment.
The selective S-type characteristic is designed to support coordinated residual-current protection where discrimination between upstream and downstream devices is required. With its 300 mA residual-current rating and 5 kA surge-current withstand capability, the F204 B S-63/0.3 is well suited to upstream protection in commercial and industrial electrical distribution systems.
Typical Applications
- Commercial and industrial electrical distribution systems.
- Three-phase installations requiring selective residual-current protection.
- Frequency converter and variable speed drive installations.
- Industrial machinery and automation systems.
- Electrical systems containing non-linear and power electronic loads.
- Distribution boards requiring coordinated upstream earth-fault protection.
