Why Choose the ABB F204 A S-40/0.1 Residual Current Circuit Breaker?
The ABB F204 A S-40/0.1 is a selective four-pole residual current circuit breaker (RCCB) designed to provide reliable earth fault protection in residential, commercial and industrial electrical installations. As part of the trusted ABB F200 RCCB series, it helps protect people, equipment and installations by detecting residual current faults and disconnecting the circuit when leakage current exceeds the rated threshold.
This Type A selective RCCB detects sinusoidal alternating residual currents and pulsating DC residual currents. Its 40 A rated current and 100 mA residual operating current make it suitable for upstream protection, distribution boards and installations where time-selective coordination with downstream residual current devices is required.
With a four-pole configuration, DIN rail mounting and compact modular construction, the F204 A S-40/0.1 is ideal for three-phase electrical systems requiring dependable residual current protection with selective tripping behaviour.
Key Advantages
- Selective four-pole RCCB for three-phase electrical installations.
- 40 A rated current for commercial and industrial distribution systems.

Selective Earth Fault Protection for Electrical Distribution
Residual current circuit breakers monitor the balance between live conductors and neutral. If leakage current to earth is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical fire and damage to connected equipment.
The selective design of the ABB F204 A S-40/0.1 makes it suitable for upstream protection where coordination with downstream RCDs is required. This helps reduce nuisance tripping and supports a more reliable protection structure across distribution boards and electrical installations.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels and switchgear assemblies.
- Three-phase low voltage power distribution systems.
- Upstream residual current protection.
- Electrical installations requiring selective RCD coordination.
- Building services, plant rooms and machinery panels.
