5SM3642-4 SIEMENS

The 5SM3642-4 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 circuits with smooth DC residual currents and AC residual currents. The 5SM3642-4 has a rated current (In) of 25A, making it suitable for a wide range of applications in residential, commercial, and industrial settings. Its sensitivity to residual current is 300mA, providing a balance between protection and minimizing nuisance tripping. The short-time delayed tripping characteristic ensures selectivity in cascaded RCCB systems, preventing unnecessary shutdowns. It is designed for a rated AC voltage (Un) of 400V. This RCCB is essential for ensuring electrical safety and preventing damage to equipment. The 5SM3642-4 offers reliable performance and contributes to a safer electrical environment. Siemens' commitment to quality and innovation is evident in the design and construction of this RCCB.
