5SV3747-5 SIEMENS

The 5SV3747-5 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is designed to detect residual currents, which are indicative of insulation failures or earth faults, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Featuring a Type B tripping characteristic, it is suitable for a wide range of applications, including those with pulsating DC residual currents. The selective tripping characteristic ensures that only the faulty circuit is disconnected, minimizing disruption to other parts of the electrical system. With a rated current (In) of 80A and a residual current (IΔn) of 500mA, this RCCB is designed for robust performance in demanding environments. It is rated for an AC voltage (Un AC) of 400V, making it compatible with standard industrial and commercial power systems. The 5SV3747-5 offers a reliable and efficient solution for enhancing electrical safety and preventing costly downtime. Its robust construction and adherence to international standards ensure long-lasting performance and peace of mind. This device is an essential component for any electrical installation where safety and reliability are paramount.
