Review on Contactor Pole Voltage for Packard C240B by Xiaomeng Chang

My air compressor is in a shed about 60 feet from my house so I don't need to hear it running. My air line burst in the middle of the night and the compressor ran for hours before I realized it. I used this relay to control the contacts on the compressor so that they are only active when the store's low voltage switch is on. I also installed a strip of red LEDs in the store that turn on when the compressor is pumping and turn off when it's full. If the LED strip stays on for too long I can go to the shed and see if there is a problem. When I finish my workday, I flip the switch in the shop knowing that the compressor won't turn on even if the pressure in the tank gets too low due to an air leak.
