Siemens Residual Current Operated Circuit Breaker Type AC 40A 3+N-Pole 300mA 400V 4M 5SV4644-0
The Siemens Residual Current Operated Circuit Breaker (RCCB) Type AC 40A 3+N-Pole 300mA 400V 4M 5SV4644-0 is a robust electrical protection device designed to provide reliable residual current monitoring and leakage fault protection in three-phase power distribution systems. Engineered for industrial, commercial, and infrastructure applications, this RCCB continuously monitors current flow across all conductors and disconnects the circuit immediately when a residual current fault is detected. With a rated current of 40A, a residual current sensitivity of 300mA, and a 400V operating voltage, the Siemens 5SV4644-0 is ideal for protecting electrical installations against earth leakage faults and reducing fire risks. Its compact 4-module design and 3+N-pole configuration make it suitable for integration into switchboards, control panels, and industrial automation systems.
