2. Frei verwendbar / © Siemens AG 2014. Alle Rechte vorbehalten. 5SU9 Residual Current Circuit Breakers with Overcurrent Protection Residual Current Operated Circuit Breakers (RCBOs) are a combination of an RCCB and MCB in a compact design for personnel, fire and line protection. For personnel protection and fire protection, the residual current part of the type AC trips in the event of sinusoidal AC residual currents, type A also trips in the event of pulsating DC residual currents. RCBOs with a rated residual current of maximum 30 mA are used for personnel, material and fire protection, as well as for protection against direct contact. The MCB part of the 5SU9 RCBOs protects lines against overload and short circuits and is available in characteristics B, C and D. RCBOs comprise one part for fault-current detection and one part for overcurrent detection. They are equipped with a delayed overload/time-dependent thermal release (thermal bimetal) for low overcurrents and with an instantaneous electromagnetic release for higher overload and short-circuit currents.
