ABB F204 AC-25/0.03 AP-R four-pole high immunity residual current circuit breaker rated at 25 A with 30 mA sensitivity.
The ABB F204 AC-25/0.03 AP-R is a high-performance four-pole residual current circuit breaker (RCCB) designed to provide reliable protection against earth leakage currents in commercial and industrial electrical installations. As part of the trusted ABB F200 RCCB series, it safeguards people and electrical equipment by disconnecting the circuit whenever dangerous leakage currents are detected.
This Type AC RCCB is designed to detect sinusoidal alternating residual currents and features ABB's AP-R high immunity technology, providing increased resistance to nuisance tripping caused by transient voltages and network disturbances. Its 25 A rated current and 30 mA residual operating current make it ideal for protecting final circuits where enhanced continuity of service is required.
Featuring a compact four-pole DIN rail mounted design, the F204 AC-25/0.03 AP-R is well suited to distribution boards, commercial switchboards and industrial control panels requiring dependable residual current protection with improved immunity to unwanted trips.
Residual current circuit breakers continuously monitor the balance between live conductors and the neutral conductor. If earth leakage occurs, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical fires and equipment damage.
ABB AP-R technology provides improved immunity against unwanted tripping caused by transient overvoltages and electrical disturbances, making the device particularly suitable for installations where continuity of service is important.
