Description
The Carrier HN52DA024A Contactor is an electrically operated switch that controls power delivery to two-pole loads such as compressors and condenser fan motors using a 24-volt AC coil energized at 50 or 60 Hz. Its electromagnetic coil pulls in the armature when the control circuit sends a signal, simultaneously closing to supply line voltage to the connected load with consistent contact pressure across each switching cycle. Wired into condensing units, heat pumps, and packaged units of HVAC systems, it fits into the high-voltage section of the electrical panel with line and load conductors.
