5SV3446-8LA SIEMENS

The 5SV3446-8LA is a 4-pole residual current operated circuit breaker (RCCB) from Siemens, designed to provide enhanced electrical safety and protection. This RCCB is a Type A device, meaning it is sensitive to both AC and pulsating DC residual currents, offering broader protection compared to Type AC RCCBs. With a rated current (In) of 63A, it is suitable for applications with moderate to high current demands. The device has a residual current tripping value of 100mA, ensuring rapid disconnection in the event of a fault, minimizing the risk of electric shock. Its selective tripping characteristic allows for coordinated protection within an electrical system, preventing nuisance tripping of upstream devices. The RCCB is designed for a rated voltage (Un AC) of 400V, making it compatible with standard three-phase power systems. Furthermore, this model incorporates thermal overload protection, safeguarding against excessive current draw that could damage connected equipment or the circuit breaker itself. This combination of residual current and thermal overload protection provides comprehensive safety for both people and equipment. Siemens is a trusted brand known for quality and reliability in electrical protection devices. The 5SV3446-8LA is suitable for a wide range of applications, including industrial, commercial, and residential settings.
