5SV3646-8 SIEMENS

The 5SV3646-8 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This device is specifically designed to detect residual currents, which indicate insulation failures or earth leakage, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Classified as a Type A RCCB, it is sensitive to both alternating current (AC) and pulsating direct current (DC) residual currents, offering enhanced protection compared to standard AC type RCCBs. With a rated current (In) of 63A, this RCCB is suitable for a wide range of applications in commercial and industrial settings. The selective tripping characteristic ensures that only the faulty circuit is disconnected, minimizing disruption to other parts of the electrical system. Its rated residual current (IΔn) is 300mA, providing a balance between sensitivity and immunity to nuisance tripping caused by transient leakage currents. The RCCB is designed for a rated voltage (Un) of 400V AC. This Siemens RCCB offers reliable and precise protection, enhancing electrical safety and preventing potential damage to equipment and infrastructure. It adheres to stringent quality standards, ensuring long-term performance and dependability.
