5SV3646-3 SIEMENS

The 5SV3646-3 is a four-pole residual current operated 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 F classification, it is particularly sensitive to mixed-frequency currents, including those with frequencies up to 1 kHz, making it suitable for modern electrical systems with electronic devices. The 5SV3646-3 incorporates a short-time delayed tripping characteristic, minimizing nuisance tripping caused by transient surges or capacitive discharge currents. With a rated current (In) of 63A, this RCCB can handle substantial electrical loads, ensuring reliable protection for a wide range of applications. Its sensitivity to residual currents is set at 300mA, providing a balance between safety and operational continuity. The device is designed for a rated AC voltage (Un AC) of 400V, making it compatible with standard three-phase power systems. This RCCB is essential for safeguarding people and equipment in residential, commercial, and industrial environments. Its robust design and adherence to stringent quality standards ensure long-lasting and dependable performance. The 5SV3646-3 offers a comprehensive solution for enhancing electrical safety and preventing potential hazards.
