5SV3444-8LA SIEMENS

The 5SV3444-8LA is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens for enhanced electrical safety and circuit protection. This device is classified as Type A, indicating its capability to detect both alternating current (AC) and pulsating direct current (DC) residual currents, offering comprehensive protection against a wider range of fault currents. Its selective functionality ensures that only the RCCB closest to the fault trips, minimizing disruption to the overall electrical system. With a rated current (In) of 40 A and a residual current (IΔn) sensitivity of 100 mA, it provides a balance between protection and operational continuity. The RCCB is designed for a rated AC voltage (Un AC) of 400 V, making it suitable for standard industrial and commercial applications. Furthermore, the integrated thermal overload protection safeguards the circuit breaker itself from damage due to excessive current, enhancing its reliability and longevity. This combination of features makes the 5SV3444-8LA an ideal choice for applications requiring both residual current and overload protection. It ensures compliance with safety standards and contributes to a safer electrical environment. Siemens' commitment to quality and innovation is evident in the design and performance of this RCCB.
