ABB F204 A S-100/1 four-pole Type A selective residual current circuit breaker rated at 100 A with 1000 mA sensitivity for three-phase electrical distribution systems.
£392.53
The ABB F204 A S-100/1 is a premium 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 protects people and equipment by detecting residual current faults while providing selective time-delayed operation for improved coordination with downstream protective devices.
This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents generated by modern electrical equipment. Its 100 A rated current and 1000 mA (1 A) residual operating current make it ideal for upstream protection in three-phase distribution systems where selective tripping is required to maximise system availability.
Featuring a compact four-pole DIN rail mounted design, robust screw terminals and ABB's proven engineering, the F204 A S-100/1 is suitable for demanding industrial switchboards, commercial distribution panels and infrastructure projects requiring reliable residual current protection.
Residual current circuit breakers continuously monitor the balance between live conductors and the neutral conductor. If earth leakage is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical fires and damage to connected equipment.
The selective operating characteristic of the ABB F204 A S-100/1 provides intentional delayed tripping compared with downstream RCCBs, improving discrimination and helping maintain continuity of service by allowing only the affected section of an installation to be isolated.

The ABB F204 A S-100/1 provides selective residual current protection for three-phase electrical installations, helping isolate earth leakage faults while coordinating with downstream RCCBs.
The 1000 mA (1 A) residual operating current is the earth leakage threshold at which the RCCB disconnects the protected circuit.
Type A RCCBs detect alternating residual currents and pulsating DC residual currents, making them suitable for modern electrical installations containing electronic equipment.
A selective RCCB provides delayed tripping to improve discrimination with downstream residual current devices, reducing unnecessary interruptions to the overall electrical installation.
The RCCB mounts directly onto a standard DIN rail inside switchboards, distribution boards and electrical control panels.
ABB F200 series RCCBs are trusted by electrical contractors, panel builders and industrial engineers worldwide for dependable residual current protection, long service life and reliable operation.
