Abstract
An overload relay, which trips a current flow between a power source and a load, includes a trip capacitor that stores therein an electric charge to excite a trip coil so as to trip the current flow, a reset capacitor that stores therein an electric charge to excite a reset coil so as to reset the tripped current flow, an energizing unit that energizes the coils, and a capacitor-diagnosing unit that diagnoses the capacitors. The energizing unit forcibly energizes the trip coil by using the trip charge when the capacitor-diagnosing unit diagnoses that there is a degradation of a property of the trip capacitor.
