An overcurrent protection device comprising an electric circuit that cuts off current to a load when the relay is open, characterized in that a positive temperature coefficient thermistor element is connected in parallel to the contacts of the relay. (2) It has an electromagnetic coil connected via a power line between the load and the power source, and a contact that opens and closes based on the amount of current flowing through this electromagnetic coil, and energizes the load by opening and closing this contact. 1. An overcurrent protection device for controlling an overcurrent, characterized in that a positive temperature coefficient thermistor element having both terminals connected to the contact point is provided integrally with the relay.
