F204 AC-125/0.03 ABB - 2CSF204001R1950 F429415

The F204 AC-125/0.03, identified by ABB part number 2CSF204001R1950 and internal code F429415, is a four-pole residual current circuit breaker (RCCB) belonging to the F200 series. This device is specifically designed to protect against AC sinusoidal alternating currents. It features a rated current (In) of 125A, indicating its capacity to handle substantial electrical loads. The sensitivity to differential current (Idn) is set at 30mA, ensuring rapid response to even small leakage currents. This RCCB operates on the principle of pure differential measurement, accurately detecting imbalances between incoming and outgoing currents. Such imbalances often signify earth faults or insulation failures, posing significant safety risks. By quickly interrupting the circuit upon detecting these faults, the F204 AC-125/0.03 minimizes the risk of electric shock and prevents potential fire hazards. Its four-pole configuration makes it suitable for three-phase systems with a neutral conductor. The device provides reliable protection in residential, commercial, and industrial applications, safeguarding both people and equipment. This RCCB is an essential component for ensuring electrical safety and compliance with relevant regulations.
