Why Choose the ABB F202 A-25/0.5 RCCB?
The ABB F202 A-25/0.5 is a 2-pole Type A residual current circuit breaker (RCCB) designed to provide residual current protection in low-voltage electrical installations. Identified by ABB order code 2CSF202101R4250, it belongs to ABB's F200 family of modular RCCBs for residential, commercial and industrial distribution systems.
Rated at 25 A with a rated residual operating current of 500 mA, the F202 A-25/0.5 monitors the protected circuit for qualifying leakage currents to earth. Its Type A characteristic provides detection of sinusoidal alternating residual currents and pulsating DC residual currents, supporting applications with a wider range of electrical and electronic loads than Type AC devices.
The 2-pole configuration provides simultaneous switching of both live conductors in single-phase circuits. Designed for modular DIN-rail distribution equipment, the F202 A-25/0.5 provides dedicated residual current protection while correctly coordinated overload and short-circuit protection is provided separately.
Key Advantages
- 25 A rated current for appropriately rated single-phase circuits.
- 500 mA residual operating current for applications requiring this earth-leakage protection threshold.
- Type A detection for sinusoidal AC and pulsating DC residual currents.
- 2-pole switching provides simultaneous disconnection of both live conductors.
- Modular format supports straightforward integration into DIN-rail distribution boards.
- Part of ABB's established F200 RCCB range.

Reliable Type A Residual Current Protection
An RCCB continuously compares the current flowing through the live conductors of a protected circuit. If leakage to earth produces a residual current that reaches the device's operating threshold, the RCCB disconnects the circuit. The ABB F202 A-25/0.5 combines a 25 A rated current with a 500 mA residual operating current for installations requiring this specific level of earth-fault protection.
The Type A characteristic allows the F202 A-25/0.5 to respond to sinusoidal alternating and pulsating DC residual currents. Its 500 mA sensitivity is not the 30 mA level normally used for additional protection against electric shock, so device selection must match the required protective function and applicable installation rules. As an RCCB, it also requires suitable separate protection against overload and short-circuit currents.
Typical Applications
- Residential and commercial electrical distribution systems.
- Industrial low-voltage distribution boards.
- Single-phase circuits requiring 500 mA residual current protection.
- Circuits requiring Type A residual-current detection.
- Electrical installations containing loads capable of producing pulsating DC residual currents.
- Modular DIN-rail protection and distribution assemblies.

Frequently Asked Questions
What is the ABB F202 A-25/0.5 used for?
The ABB F202 A-25/0.5 is a 2-pole Type A RCCB designed to provide residual current protection by disconnecting the protected circuit when qualifying earth leakage reaches its 500 mA operating threshold.
What is the rated current of the F202 A-25/0.5?
The ABB F202 A-25/0.5 has a rated current of 25 A.
What residual current sensitivity does the F202 A-25/0.5 have?
The F202 A-25/0.5 has a rated residual operating current of 500 mA. This differs from the 30 mA sensitivity commonly used where additional protection against electric shock is required.
What does Type A mean on the ABB F202 A-25/0.5?
Type A means the RCCB can respond to sinusoidal alternating residual currents and pulsating DC residual currents. This makes Type A suitable for circuits where connected equipment can generate these residual-current waveforms.
Does the ABB F202 A-25/0.5 provide overload and short-circuit protection?
No. The F202 A-25/0.5 provides residual current protection but does not incorporate overload or short-circuit protection. Suitable overcurrent protection must therefore be provided separately and coordinated with the RCCB.
Trusted ABB Type A Residual Current Protection
ABB F200 Type A residual current circuit breakers provide dedicated earth-fault protection for modern low-voltage installations, combining detection of AC and pulsating DC residual currents with a compact modular format for professional electrical distribution systems.
