  • Mag switch search

    Can anyone give me some leads on where I might find a magnetic start switch for a 220 single phase motor?
    I have a 3 hp, or 5 hp motor I can use. The 3 hp is a better choice except for the 5 obviously has more hp
    busy bee has one rated for 3 hp,that’s all I have found

    have a danfoss for 220 volts 75.00
    it will need a larger overload sized for your motor application
    think that is about 40 to 50
    its a 225.00switch new

          King Canada sells them. You can get them in different voltage and amp ratings

          Just bought 2 yesterday from Brettwood Machinery.

            the overload is the amp setting for the motor. it trips out at the value. i think you set it to
            the motor value plus 10 or 15 percent

            example motor 10amps set overload to11 to 12 amps
            overloads usually have a range 10 to 16 amps
            8 to 12 amps etc..

            the switches i have a lower ranges like 7 amps suitable for lower hp motors say 1 or 3/4hp
            you would need to change the overload to suit your application
            phone a motor shop etc...
