5SV4346-0MB SIEMENS

The 5SV4346-0MB is a 4-pole residual current operated circuit breaker (RCCB) designed and manufactured by Siemens. This RCCB is a crucial safety device engineered to protect electrical circuits and prevent electrical shocks. It instantly detects residual currents, also known as earth leakage currents, and interrupts the circuit to minimize the risk of injury or fire. The device is rated for a current of 63A and is designed to trip at a residual current of 30mA, ensuring rapid response to leakage events. It is suitable for AC systems with a rated voltage of 400V. The 5SV4346-0MB is classified as a Type AC RCCB, meaning it is designed to detect sinusoidal alternating residual currents. This device is commonly used in residential, commercial, and industrial applications to provide enhanced electrical safety. Its reliable performance and compliance with safety standards make it an essential component in modern electrical installations. This RCCB contributes significantly to preventing electrical accidents and ensuring the safety of people and equipment.
