5SV3646-8LA SIEMENS

The 5SV3646-8LA is a 4-pole residual current operated circuit breaker (RCCB) from Siemens, designed to provide enhanced electrical safety and protection. This device is a Type A RCCB, meaning it is sensitive to both alternating current (AC) and pulsating direct current (DC) residual currents, offering broader protection against various fault types. With a rated current (In) of 63 A, it is suitable for applications with moderate to high current demands. The RCCB has a tripping current (IΔn) of 300 mA, providing a balance between sensitivity and avoiding nuisance tripping. Its selective characteristic ensures that only the RCCB closest to the fault trips, minimizing disruption to the overall electrical system. The rated voltage (Un) is 400 V AC, making it compatible with standard three-phase power systems. Furthermore, this RCCB incorporates thermal overload protection, safeguarding against excessive current draw that could damage connected equipment or the circuit breaker itself. This comprehensive protection makes the 5SV3646-8LA a reliable choice for ensuring safety and preventing electrical hazards in diverse applications. It adheres to industry standards for safety and performance.
