2CSF204001R4400 ABB - F204 AC-40/0,5

The 2CSF204001R4400, also known as the ABB F204 AC-40/0,5, is a four-pole residual current circuit breaker (RCCB) designed for reliable protection against electrical faults. As part of the F200 series, this RCCB is specifically engineered to detect AC sinusoidal alternating currents. It features a rated current (In) of 40A, making it suitable for a variety of applications in residential, commercial, and industrial settings. The device's sensitivity to residual current (Idn) is 500mA, ensuring prompt tripping in the event of a ground fault, thereby minimizing the risk of electric shock and fire hazards. The F204 AC-40/0,5 operates as a 'pure differential type' switch, meaning it directly measures the difference between incoming and outgoing currents. This direct measurement provides accurate and dependable fault detection. Its four-pole configuration allows it to interrupt all four conductors (three phases and neutral) in a three-phase system, providing comprehensive protection. This RCCB is essential for ensuring electrical safety and compliance with regulatory standards. It offers a robust and dependable solution for protecting circuits and preventing electrical accidents. The ABB F204 AC-40/0,5 is a vital component in any electrical installation where safety and reliability are paramount.
