ABB F204 A S-100/0.1 four-pole Type A selective residual current circuit breaker rated at 100 A with 100 mA sensitivity for three-phase electrical distribution systems.
£467.08
The ABB F204 A S-100/0.1 is a high-performance four-pole selective residual current circuit breaker (RCCB) designed to provide dependable earth fault protection in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 RCCB series, it helps protect people, equipment and installations by disconnecting the circuit when residual current exceeds the rated threshold.
This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents. Its 100 A rated current and 100 mA residual operating current make it suitable for upstream protection in three-phase distribution systems where selective coordination with downstream residual current devices is required.
With its four-pole DIN rail mounted design, robust screw terminals and compact modular housing, the F204 A S-100/0.1 is ideal for professional switchboards, distribution panels and control systems requiring reliable residual current protection with delayed selective tripping behaviour.
Residual current circuit breakers continuously monitor the current balance between live conductors and neutral. If earth leakage is detected, the RCCB disconnects the protected circuit to help reduce the risk of electric shock, electrical fire and equipment damage.
The selective operating characteristic of the ABB F204 A S-100/0.1 provides intentional delayed tripping, helping improve coordination with downstream residual current devices. This supports continuity of service by allowing downstream protection to operate first where appropriate.

The ABB F204 A S-100/0.1 is used to provide selective residual current protection in three-phase electrical installations, helping isolate earth leakage faults while coordinating with downstream protective devices.
The 100 A rated current indicates the maximum current the RCCB is designed to carry continuously under normal operating conditions.
The 100 mA residual operating current is the earth leakage threshold at which the RCCB is designed to disconnect the circuit.
A selective RCCB uses time-delayed tripping to improve discrimination with downstream residual current devices, helping reduce unnecessary upstream power interruptions.
The RCCB mounts directly onto a standard DIN rail within distribution boards, switchboards and electrical control panels.
ABB F200 series residual current circuit breakers are widely trusted by electrical contractors, panel builders and maintenance engineers for dependable earth fault protection across commercial and industrial installations.
