5SV3644-7 SIEMENS

The 5SV3644-7 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is specifically designed to detect residual currents, which are indicative of insulation failures or ground faults, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Featuring a Type F classification, it is particularly sensitive to mixed-frequency currents, including those with frequencies up to 1 kHz, offering enhanced protection against modern electronic devices. The 'selective' characteristic ensures that only the faulty circuit is disconnected, minimizing disruption to other parts of the electrical system. With a rated current (In) of 40 A and a residual current tripping value (IΔn) of 300 mA, this RCCB is suitable for a wide range of applications in industrial and commercial settings. It is designed for a rated voltage (Un) of 400 V AC. This device adheres to stringent quality standards, ensuring reliable and consistent performance. Its robust construction guarantees a long service life, even in demanding environments. The 5SV3644-7 offers a dependable solution for safeguarding people and equipment from electrical hazards.
