The Siemens 5SV4444-0RC is a SENTRON 5SV series RCCB (Residual Current Circuit Breaker) designed to provide reliable protection against earth leakage currents in low-voltage electrical systems. It helps prevent electric shock hazards and electrical fire risks by automatically disconnecting the supply when leakage current exceeds the safe limit.
This device is commonly used in industrial, commercial, and distribution board applications where high safety and compliance with IEC standards is required.
