Description
The Siemens Industrial Controls 40DP32AF Contactor, 3-phase 120V AC suitable for switching circuits. It works at 120V and it has an electromagnetic coil; when energized, it establishes a magnetic field that causes the main contacts to make, allowing current to flow to the connected equipment. it is done by de-energizing the coil, which in turn opens these contacts and breaks the circuit. This contactor is widely used in HVAC systems to regulate the power supply to the compressors, fans, and heating elements.
