    I am trying to get the necessary protective relays for my generator system and I do not want to use relays with a electromechanical output relay as this does not last as long. I am trying to locate these and am having some trouble with it. Is there anyone who knows about this?
    The following relays will need the following specs:
    3 phase 120/208 volt system prefer no coil voltage necessary but 12/24 volt if necessary.
    Adlustable trip time and adjustable automatic reset time. Need two poles each that open on fault.
    Overvoltage
    Undervoltage
    Overfrequency
    Underfrequency
    Loss of phase
    Overcurrent
