摘要： A magnetic circuit includes a stationary iron core, a permanent magnet, and an armature, in a circular pattern. A contact mechanism spring separates the armature from the stationary iron core to open the magnetic circuit to switch a contact mechanism to a reset position. A coil on the magnetic circuit generates a magnetic flux in a direction same as that of the permanent magnet when an overload is detected and in an opposite direction when a predetermined time is elapsed after detecting the overload. A reset bar switches a movable stopper between an engaging position and a non-engaging position with the contact mechanism against a biasing force of the contact mechanism spring.

摘要： 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.
