Packard C440B 4-Pole Contactor 120V 40AMP

The Packard C440B Contactor Coil is a definite-purpose electrical switching component used in the HVAC systems to control high-voltage loads such as compressors, condenser fans, and heating elements. It operates with a 120V coil that energizes an internal magnetic mechanism, allowing the four-pole contacts to safely switch up to 40 amps of electrical load in a 208/240V systems. Built for refrigeration equipment, it provides accurate separation between the low-voltage control signals and high-power circuits. Installed in outdoor condensing units and air handlers, it ensures the consistent switching performance and safe system operation under the continuous duty conditions.
