Abstract
An electromagnetic relay includes an electromagnet device, a contact device, and a trip device. The electromagnet device includes a first stator, a movable element, and a first exciting coil. The contact device includes a movable contact and a fixed contact. A trip device includes a second exciting coil. The electromagnet device moves the movable element from a first position to a second position. The trip device moves the movable element to a third position. An open state is reached when the movable element is in the first position and the third position. A closed state is reached when the movable element is in the movable element is in the second position.
