Resideo DP2040A1003 2-Pole Economy Definite Purpose Contactor 40A 24V

The Resideo DP2040A1003 is a 2-pole, 40 amp contactor designed for efficient and reliable operation in heating, ventilation, and air conditioning (HVAC) systems. It acts like a heavy-duty switch, controlled by a low-voltage (24V) electrical signal. When activated, the contactor opens and closes circuits, turning on or off higher-powered equipment like compressors, heaters, or ventilation fans. This allows a low-voltage control system to safely manage powerful devices. The DP2040A1003 is an economical contactor, well-suited for various HVAC applications. It can handle up to 40 amps of current and is compatible with a wide range of temperatures, from -4°F to 149°F. While not designed for reversing electrical current (non-reversing), it operates on both 50Hz and 60Hz electrical grids. The contactor itself is lightweight, weighing only 0.52 pounds.
