Why Choose the ABB FH204 AC-25/0.3 RCCB?
The ABB FH204 AC-25/0.3, order code 2CSF204006R3250, is a reliable 4-pole Type AC residual current circuit breaker (RCCB) designed to provide residual current protection in electrical distribution systems. As part of the established ABB F200 / FH200 RCCB product group, it provides dependable earth leakage protection for residential, commercial and light industrial applications.
This RCCB has a rated current of 25 A and a rated residual operating current of 300 mA. Its Type AC characteristic is designed to detect sinusoidal alternating residual currents, making it suitable for appropriately designed circuits where this residual current waveform is expected.
The 4-pole configuration makes the FH204 AC-25/0.3 suitable for three-phase electrical distribution circuits requiring residual current protection across four conductors. Its modular DIN rail construction enables straightforward integration into distribution boards for new installations, upgrades and replacement applications.

Type AC Residual Current Protection
Residual current circuit breakers monitor the balance of current flowing through an electrical circuit and disconnect the supply when residual current to earth reaches the device's operating threshold. The ABB FH204 AC-25/0.3 provides 300 mA residual current sensitivity for applications where Type AC protection is appropriate, helping protect electrical installations against earth leakage faults.
The FH204 AC-25/0.3 is an RCCB and does not incorporate overload or short-circuit protection. Suitable overcurrent protection must therefore be provided separately in accordance with the electrical installation design and applicable requirements. Its 300 mA sensitivity should also be distinguished from 30 mA devices typically specified where additional protection against electric shock is required.
Typical Applications
- Residential electrical distribution systems.
- Commercial electrical installations.
- Light industrial distribution systems.
- Three-phase circuits requiring 4-pole residual current protection.
- Building services and electrical distribution equipment.
- Circuits where Type AC residual current protection is appropriate.
- Installations requiring 300 mA residual current sensitivity.

Frequently Asked Questions
What is the ABB FH204 AC-25/0.3 used for?
The ABB FH204 AC-25/0.3 is a 4-pole Type AC RCCB designed to provide residual current protection in electrical distribution systems where sinusoidal AC residual currents may occur.
What are the current and residual current ratings of the FH204 AC-25/0.3?
The RCCB has a rated current of 25 A and a rated residual operating current of 300 mA.
What does Type AC mean on this ABB RCCB?
Type AC means the RCCB is designed to detect sinusoidal alternating residual currents.
Is the FH204 AC-25/0.3 a 30 mA RCCB?
No. The FH204 AC-25/0.3 has a rated residual operating current of 300 mA. Where 30 mA additional protection is required, an appropriately specified 30 mA residual current protective device should be selected.
Does the ABB FH204 AC-25/0.3 provide overload protection?
No. The FH204 AC-25/0.3 is an RCCB providing residual current protection, so appropriately rated overcurrent protection must be provided separately where required for overload and short-circuit protection.
