5SM3648-2 SIEMENS

The 5SM3648-2 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens for comprehensive electrical protection. This RCCB is classified as type AC, indicating its suitability for detecting alternating current residual currents. Its selective functionality ensures that only the faulty circuit is disconnected, minimizing disruption to other operational circuits. With a rated current (In) of 100 A, it can handle substantial electrical loads. The device is designed to trip at a residual current of 300 mA, providing a balance between sensitivity and nuisance tripping prevention. It is rated for an AC voltage (Un AC) of 400 V, making it compatible with standard industrial and commercial power systems. This RCCB offers reliable protection against earth fault currents, preventing electrical shocks and fire hazards. Its robust construction and adherence to stringent quality standards ensure long-term performance and dependability. The 5SM3648-2 is an essential component for ensuring electrical safety in diverse applications.
