It is an object to provide is an overcurrent relay having less number of parts and a smaller space to implement an automatic reset function and a manual reset function. A contact point mechanism 110 includes a movable contactor support 10 for supporting a movable contactor composing a part of the usually-closed contact point while being maintained in the movable iron core 5, and a reset bar 14 arranged in a manner that is switchable between an automatic reset setting and a manual reset setting. The reset bar 14 does not engage with the movable contactor support 10 in an operation range of the movable contactor support 10 in the automatic reset setting. In addition, the reset bar 14 engages with the movable contactor support 10 in interlock with the movable iron core 5 to interrupt the reset operation of the movable iron core 5 of the electromagnet 109 in the manual reset setting, and, when the reset operation is manually performed, engages with the movable contactor support 10 to be moved up to a position at which the reset operation is completed.
