ABB F204 A-40/0.03 – 4-pole residual current circuit breaker for reliable residual current protection
The ABB F204 A-40/0.03 is a robust 4-pole residual current circuit breaker (RCCB) for safe electrical installations. It trips at a fault current of 30 mA and is designed for rated currents up to 40 A. Therefore, it is a proven choice for new installations, renovations, and extensions.
Your benefits at a glance
-
Personal protection: A 30 mA tripping current reliably protects against dangerous touch currents.
-
Pulse current sensitive (Type A): Detects alternating fault currents and pulsating direct fault currents – for modern electronics.
-
Screw terminals: Proven and safe connection technology for conductor cross-sections up to 35 mm².
-
Space-saving: Compact 4-TE design (70.0 mm) for DIN rail mounting.
-
ABB quality: Tested according to IEC/EN 61008 and approved for worldwide use.
Protective function and use
Type A residual current devices (RCDs) detect both sinusoidal alternating currents and pulsating direct currents. This makes them suitable for circuits with modern electronic devices such as LED dimmers, switched-mode power supplies, or induction cooktops. The rated residual current of 30 mA provides personal protection against direct and indirect contact, minimizing the risk of a dangerous electric shock. Experts also recommend regularly testing the RCD using the test button.

Assembly and wiring
The F204 A-40/0.03 simply snaps onto a 35 mm DIN rail. You then connect the conductors using the screw terminals. Power can be fed in from both the top and bottom. Additionally, you can connect the residual current device (RCD) to the ABB PS busbar system. This eliminates the need for complex individual wiring. Furthermore, the test button simplifies regular functional testing.
