5SV3646-8KL SIEMENS

The 5SV3646-8KL is a four-pole residual current operated circuit breaker (RCCB) from Siemens, designed to provide enhanced protection against electrical faults. This RCCB is a type A device, meaning it is sensitive to both AC and pulsating DC residual currents, offering a broader range of protection compared to type AC RCCBs. With a rated current (In) of 63A, it is suitable for applications with higher current demands. The tripping current (IΔn) is 300mA, providing a balance between sensitivity and nuisance tripping prevention. Its selective characteristic ensures that only the faulty circuit is disconnected, minimizing disruption to other circuits. The rated voltage (Un) is 400V AC, making it compatible with standard three-phase power systems. This RCCB is designed with the neutral (N) connection on the left side. It offers reliable protection against residual currents, preventing electrical shocks and fire hazards. It is suitable for industrial and commercial applications. This device contributes to a safer electrical installation.
