Contactors are essential components in HVAC systems, acting as electrically-controlled switches that enable the flow of high-voltage current to compressors, condenser fans, and other major components. When energized by the control circuit, the contactor closes to allow power to reach the equipment; when de-energized, it opens to safely disconnect power. This Trane contactor is engineered to withstand the demanding cycles of commercial heating and cooling applications.
