5SU1656-7KK13 SIEMENS

The 5SU1656-7KK13 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both overload/short circuit and residual current faults. This RCBO has a breaking capacity of 6 kA, suitable for standard residential and commercial applications. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The device is a type A RCBO, which is sensitive to both AC and pulsating DC residual currents, offering enhanced safety. With a residual current tripping sensitivity of 300 mA, it provides a balance between protection against electric shock and nuisance tripping. The RCBO has a C-characteristic tripping curve, making it suitable for circuits with moderate inrush currents. Its rated current (In) is 13 A, and it is designed for a rated AC voltage (Un AC) of 230 V. This RCBO combines the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit, saving space in the distribution board and simplifying installation. It is ideal for protecting circuits supplying lighting, sockets, and other general-purpose loads in residential, commercial, and industrial environments, ensuring safety and compliance with electrical standards.
