5SV3644-6KL SIEMENS

The 5SV3644-6KL is a 4-pole residual current operated circuit breaker (RCCB) from Siemens, designed to protect against electrical shocks and fire hazards. This RCCB is a Type A device, meaning it is sensitive to both AC and pulsating DC residual currents. It has a rated current (In) of 40A, indicating the maximum current it can continuously carry without tripping. The residual current tripping value (IΔn) is 300mA, which is the threshold at which the RCCB will trip to interrupt the circuit, providing protection against leakage currents. It is designed for a rated voltage (Un) of 400V AC, suitable for standard three-phase power systems. The 'N left' designation indicates the position of the neutral conductor connection on the left side of the device. This RCCB is essential for ensuring electrical safety in residential, commercial, and industrial applications. It promptly disconnects the power supply upon detecting a fault current, minimizing the risk of electric shock and preventing potential fires. Siemens RCCBs are known for their reliability and adherence to stringent safety standards, making them a trusted choice for electrical protection.
