Description
The York S1-02425965000 Contactor is an electrically controlled part used to control power flow to equipment using a low-voltage signal in HVAC systems. It works by a 24V coil that creates a magnetic field and a 2-pole, 20A, 50/60Hz switch to close the connections and allow current to pass to connected components such as compressors or fan motors and then opens when disconnected. It is used in air conditioners, heat pumps, and refrigeration systems where consistent switching is required. Its operation improved electrical protection, and efficient power control, helping maintain stable performance in systems.
