2CSF204201R3400 ABB - F204 A S-40/0,3

The 2CSF204201R3400 ABB - F204 A S-40/0.3 is a four-pole residual current device (RCD) from the F200 series, designed to protect against electrical shocks and fire hazards caused by earth faults. This device is a pure S-type differential protection, which means it is specifically designed for sinusoidal currents and continuous DC components. It features selective tripping, ensuring that only the faulty circuit is disconnected, minimizing disruption to other circuits. The rated current (In) is 40A, indicating the maximum current the device can handle continuously. The rated residual current (Idn) is 300mA, representing the sensitivity of the device to earth leakage currents. It is equipped with push-to-test buttons for regular functional testing, ensuring the device is operating correctly. The F204 A S-40/0.3 provides reliable protection in residential, commercial, and industrial applications. This RCD is essential for ensuring electrical safety and preventing accidents. Its robust design and compliance with international standards make it a dependable choice for any electrical installation.
