5SU1653-7KK32 SIEMENS

The 5SU1653-7KK32 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both short circuits and residual currents. This RCBO offers a breaking capacity of 4.5 kA, ensuring reliable interruption of fault currents to prevent damage to equipment and wiring. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, making it suitable for single-phase applications. The device is a type A RCBO, which is sensitive to both AC and pulsating DC residual currents, offering enhanced protection against a wider range of fault conditions. With a residual current tripping sensitivity of 300 mA, it provides a balance between protection against electrical shock and minimizing nuisance tripping. The RCBO has a C-characteristic tripping curve, making it suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. It is rated for a nominal current (In) of 32 A and a nominal AC voltage (Un AC) of 230 V. This RCBO is designed for use in residential, commercial, and industrial applications to protect people and equipment from electrical hazards. Its compact design allows for easy installation in distribution boards and consumer units.
