Why Choose the ABB F204 A-125/0.3-L RCCB?
The ABB F204 A-125/0.3-L, order code 2CSF204123R3950, is a 4-pole Type A residual current circuit breaker (RCCB) designed to provide dependable residual current protection in higher-current three-phase electrical distribution systems. Part of the established ABB F200 / FH200 RCCB product group, it is suitable for commercial, industrial and building-services installations requiring Type A residual current protection.
This RCCB has a rated current of 125 A and a rated residual operating current of 300 mA. Its Type A characteristic enables detection of sinusoidal AC residual currents and pulsating DC residual currents, making it appropriate for circuits containing many common electrical and electronic loads.
The 4-pole configuration supports three-phase electrical distribution applications, while the -L configuration provides the neutral connection on the left. Its modular DIN rail construction allows integration into compatible distribution boards where a high-current 125 A, 300 mA Type A RCCB is required.
Key Advantages
- Reliable ABB Type A residual current protection for professional electrical installations.
- High 125 A rated current for demanding distribution applications.
- 300 mA residual current sensitivity for earth leakage protection.
- Detects both sinusoidal AC and pulsating DC residual currents.
- 4-pole configuration for three-phase electrical distribution.
- Left-side neutral configuration for compatible distribution board layouts.
- DIN rail mounting for integration into modular electrical distribution systems.
Key Features
- ABB F200 series RCCB.
- Type A residual current characteristic.
- 4-pole configuration.
- 125 A rated current.
- 300 mA rated residual current.
- Detection of sinusoidal AC residual currents.
- Detection of pulsating DC residual currents.
- Left-side neutral arrangement.
- Suitable for higher-current three-phase distribution applications.
- DIN rail mounting for professional modular installations.
- Part of the established ABB F200 / FH200 RCCB product group.
High-Current Type A Residual Current Protection
Type A RCCBs are designed to respond to both sinusoidal alternating residual currents and pulsating DC residual currents. This makes the ABB F204 A-125/0.3-L suitable for appropriately designed circuits where electronic equipment may produce pulsating DC earth leakage in addition to conventional AC residual currents.
With its 125 A current rating and 300 mA residual operating threshold, this model is intended for higher-current distribution applications requiring this level of residual current protection. The F204 A-125/0.3-L is an RCCB and does not provide overload or short-circuit protection by itself, so suitable overcurrent protection must be provided separately. Its 300 mA sensitivity should also be distinguished from 30 mA devices typically specified where additional protection against electric shock is required.
Typical Applications
- Commercial electrical distribution systems.
- Industrial electrical installations.
- Higher-current three-phase distribution boards.
- Building services and infrastructure distribution systems.
- Three-phase circuits requiring 4-pole Type A residual current protection.
- Installations requiring a left-side neutral connection.
- Circuits containing equipment capable of producing pulsating DC residual currents.
- Installations requiring 125 A, 300 mA residual current protection.
