5SV3346-4 SIEMENS

The 5SV3346-4 is a four-pole residual current circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is specifically designed to detect residual currents, which are indicative of insulation failures or earth faults, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Featuring a Type B tripping characteristic, it is suitable for circuits with sensitive electronic equipment where pulsating DC residual currents may occur. The short-time delayed tripping mechanism ensures selectivity in cascaded RCCB systems, preventing nuisance tripping and maintaining operational continuity. With a rated current (In) of 63A, this RCCB can handle substantial electrical loads, making it ideal for industrial and commercial applications. Its sensitivity to residual currents is set at 30mA, providing a high level of protection against potentially dangerous leakage currents. The device is designed for a rated AC voltage (Un AC) of 400V, aligning with standard European power systems. The 5SV3346-4 offers reliable and precise protection, enhancing electrical safety and minimizing downtime. It is an essential component for modern electrical installations prioritizing safety and operational efficiency. This RCCB adheres to stringent quality standards, ensuring long-term reliability and performance.
