5SV3444-6LA01 SIEMENS

The 5SV3444-6LA01 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide comprehensive protection against electrical faults. This RCCB is specifically designed as a Type A device, making it sensitive to both alternating current (AC) and pulsating direct current (DC) residual currents. It features a short-time delayed response, which enhances its ability to discriminate between transient fault currents and sustained leakage currents, minimizing nuisance tripping. With a rated current (In) of 40 A and a residual current sensitivity (IΔn) of 100 mA, this RCCB is ideally suited for applications where a balance between safety and operational continuity is crucial. The device is designed for a rated AC voltage (Un AC) of 400 V, making it compatible with standard industrial and commercial power systems. Furthermore, the 5SV3444-6LA01 incorporates thermal overload protection, safeguarding the circuit from excessive current draw that could lead to overheating and potential damage. This integrated overload protection complements the residual current protection, providing a comprehensive safety solution. Siemens' commitment to quality ensures that this RCCB offers reliable performance and long-term durability. It is an essential component for ensuring electrical safety in a wide range of applications.
