The Siemens 5SU9356-2CN16 is a combined residual current and overcurrent protective device (RCBO) in a 1+N pole format. It provides both earth leakage protection and short-circuit/overload protection in a single DIN-rail module, sized for final sub-circuits in commercial or industrial distribution boards. The residual current element is type AC, meaning it detects sinusoidal AC earth faults only.
