5SM3648-0 SIEMENS

The 5SM3648-0 is a four-pole residual current circuit breaker (RCCB) designed and manufactured by Siemens. This RCCB is engineered to provide comprehensive protection against electrical faults, specifically residual currents, in electrical installations. It is classified as a Type AC RCCB, making it suitable for detecting sinusoidal alternating residual currents. With a rated current (In) of 100A, this device can handle substantial electrical loads, making it appropriate for industrial and commercial applications. The sensitivity of the RCCB is 300mA, meaning it will trip and interrupt the circuit when a residual current of 300mA or higher is detected, preventing electrical shocks and fire hazards. It is designed for a rated voltage (Un AC) of 400V, which is standard for three-phase power systems commonly used in industrial and commercial settings. The four-pole configuration ensures that all live conductors, including the neutral, are disconnected in the event of a fault, enhancing safety. The 5SM3648-0 RCCB is essential for ensuring compliance with safety regulations and protecting people and equipment from electrical hazards. Its robust design and reliable performance make it a trusted choice for electrical protection in diverse applications. Siemens is a reputable company known for its high-quality electrical products.
