<p>It is possible to provide an overcurrent relay capable of reducing the number of parts required for configuring automatic reset and manual reset and reducing the space required for the configuration. A contact mechanism section (110) comprises a movable contact support (10) for holding a movable contact constituting a part of a normally closed contact and being held by a movable core (5), and a reset rod (14) arranged variably in case of automatic reset and manual reset. Upon automatic reset, the reset rod (14) is not engaged with the movable contact support (10) in the operational range of the movable contact support (10), upon manual reset, the reset rod (14) is engaged with the movable contact support (10) interlocked with the movable core (5) for reset operation of the movable core (5) of an electromagnet section (109) to prevent its operation. Upon manual reset operation, the reset rod (14) can be engaged with the movable contact support (10) to move it up to a position for completing the reset operation.</p> |
