The Trane CTR2765 is a contactor that has three poles; its purpose is to work as a switch for major loads of heating and cooling systems. This controls a lot bigger currents (up to 40A) employing a simple coil signal at 24V voltage. This isolates the control circuit from the high-power circuit to make operations of HVAC equipment safe and efficient. The Trane is compact and light so fitting it into different HVAC units is easy. The several benefits of using this contactor include space-saving, efficiency in the switching of high currents, and safety and reliable.
