A circuit for use with a contactor including at least one contact is provided. The circuit includes a first segment including a voltage source, a first coil, a second coil, and a first transistor, wherein the first segment is configured to selectively conduct a closing current through the first coil, the second coil, and the first transistor to close the at least one contact. The circuit further includes a second segment including the first coil, a second transistor, and a first diode, wherein the second segment is configured to selectively conduct a holding current through the first coil, the second transistor, and the first diode to hold the at least one contact closed, and wherein the first diode is arranged such that substantially all current produced by the voltage source flows through the first coil. |
