5SV3347-4KK14 SIEMENS

The 5SV3347-4KK14 from Siemens is a 4-pole residual current operated circuit breaker (RCCB) designed to provide enhanced protection against electrical hazards. This RCCB is a Type B+ device, offering sensitivity to both AC and DC residual currents, making it suitable for applications with electronic devices that may generate DC fault currents. With a rated current (In) of 80A, it can handle substantial electrical loads. The device has a sensitivity of 30mA, ensuring rapid tripping in the event of a ground fault, minimizing the risk of electric shock. Its short-time delayed tripping characteristic allows for discrimination in cascaded circuit breaker systems, preventing nuisance tripping due to transient faults. The RCCB is designed for a rated voltage (Un AC) of 400V, making it compatible with standard industrial and commercial power systems. This RCCB provides reliable protection against residual currents, enhancing safety and preventing electrical accidents. It is suitable for a wide range of applications, including industrial, commercial, and residential settings. The 5SV3347-4KK14 contributes to a safer electrical environment by quickly disconnecting the circuit upon detection of a fault current.
