ABB F204 A S-40/0.1 four-pole Type A selective residual current circuit breaker rated at 40 A with 100 mA sensitivity for three-phase electrical distribution systems.
£302.87
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.
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.

The ABB F204 A S-40/0.1 is used to provide selective residual current protection in three-phase electrical installations, helping disconnect circuits when earth leakage faults are detected.
The 100 mA residual operating current indicates the earth leakage threshold at which the RCCB is designed to trip.
Type A RCCBs detect sinusoidal alternating residual currents and pulsating DC residual currents, making them suitable for many modern electrical installations.
Selective RCCBs are designed with delayed tripping behaviour to help coordinate with downstream residual current devices and reduce unwanted upstream disconnection.
The RCCB mounts directly onto a standard DIN rail within distribution boards, switchboards and electrical control panels.
ABB F200 residual current circuit breakers are widely trusted by electrical contractors, panel builders and maintenance engineers for dependable earth fault protection across residential, commercial and industrial installations.
