RCBO JEL5A is with enhanced sensibility and fast - operating protection devices applicable in circuits with harmonic or direct pulsating current component presence RCBO JEL5A is mainly used for AC 50Hz or 60Hz, rated voltage 230 or below and rated working current 40A or below and immediately cut off power supply once someone suffers from electric shock or leakage current above specified value. It is a combination of automatic circuit breaker and residual current electromagnetic device. It combines the properties of the two elements. The circuit breaker reacts at short circuit or overload in the protected circuit, and the electromagnetic residual current device- at failure in the conductors’ insulation. It compares the magnitude of the currents through the neutral and phase conductors. The conductors are coiled on toroid and together with the secondary winding form a measurement transformer. The power conductors are coiled in such a way that the magnetic fields generated at electrical current flow through them are mutually neutralized. At failure in the insulation of some of the conductors or at presence of a person under voltage, the system is mis-balanced and the magnetic fields can not be neutralized. This residual magnetic field generates in the secondary current winding, called current leakage. When the value of this current exceeds the limit value of the residual current breaker the device breaks and the residual current device switches off from the power supply grid. The device operates without any extra power supply to the electromagnetic residual current and is not influenced by voltage varying or decreasing.
