IL 5SU1356-7KK10series are RCBOs in compact design with a rated residual current of up to 30 mA for protection against persons, material and fire, as well as direct contact protection. The RCBO consists of a section for fault current detection and a section for overcurrent detection. They are equipped with a delayed overload/time dependent thermal release (thermal bimetal) for low overcurrents and an instantaneous electromagnetic release for higher overload and short circuit currents.
