5SV3644-3 SIEMENS

The 5SV3644-3 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 occur when current leaks to earth, and promptly interrupt the circuit to prevent electrical shock and fire hazards. Classified as a Type F RCCB, it is particularly sensitive to mixed frequencies, including those generated by modern electronic devices. The 5SV3644-3 features a short-time delayed tripping characteristic, which enhances its selectivity in complex electrical installations by preventing nuisance tripping caused by transient fault currents. With a rated current (In) of 40A, this RCCB is suitable for applications with moderate current demands. It has a residual current sensitivity of 300mA, offering a balance between protection and operational reliability. The device is designed for a rated AC voltage (Un AC) of 400V, making it compatible with standard three-phase power systems. Its four-pole configuration ensures comprehensive protection for all phases and the neutral conductor. The Siemens 5SV3644-3 is an essential component for ensuring electrical safety in residential, commercial, and industrial environments, providing reliable protection against residual current faults.
