How does pressing the reset button on an overload relay affect the current path?

Pressing the reset button on an overload relay is designed to restore the current path for the control circuit, allowing normal operation to resume. When an overload condition occurs, the relay trips, interrupting the flow of current and protecting the circuit from damage. By pressing the reset button, the relay is reset to its initial state, which re-establishes the current path. This action effectively allows the system to operate again without permanent alteration to the circuit.

The other responses do not accurately capture the function of the reset button. Disconnecting the load completely or interrupting the current supply would refer to actions taken when an overload occurs, not the resetting of the relay. Similarly, modifying the circuit permanently does not align with the reset function, as that would imply a fundamental change to the circuit configuration, which is not the case when simply resetting an overload relay.
