PURPOSE: A multifunctional overcurrent relay for testing durability of a capacitor is provided to display easily a current value, an overtime value, a short value, and a leakage current value according to an operation of the multifunctional overcurrent relay by using a display device. CONSTITUTION: A multifunctional overcurrent relay for testing durability of a capacitor includes a terminal portion(60), a fuse/leakage current circuit breaker(10), a current meter(30), a micro computer(40), and an output terminal(50). The terminal portion(60) receives the power from a power switch(PS) and supplies the driving power to each component. The fuse/leakage current circuit breaker(10) is connected to the terminal portion(60) to prevent the overload and the leakage current. The current meter(30) is used for measuring a current value within the relay by using the power of the terminal portion(60). The micro computer(40) is used for displaying the current value, an overtime value, a short value, and a leakage current value according to an operation of the relay. The output terminal(50) is used for connecting electronic components to each other.
