    I have searched the internet but not entirely comfortable on the results to order a replacement. The parts sheet for the Heat Pump on the contactor shows: CSG part# CTR-0639 with the following description: Single Pole normally open with thru bar. Contacts 240V, FLA 25.0, LRA 150.0; Coil 24V

    On the old contactor itself that has a large sticker on it: reading left to right-
    General Electric
    Volts AC 277 480 600
    Full Load Amperes 35
    Locked Rotor Amperes:
    >>1 PH (Blank)
    >> Per? ( rubbed thru)150 125 100
    Resistive Amperes Per Pole 35

    At the very bottom on the same tag: CR353CB3AH1AG

    Very small white tag near the contactor's mounting base: ;
    24v 60hz
    24v 50hz
    55-827h

    Power contactors / definate purpose contactors for condenser units are pretty generic .

    As long as the replacement contactor will phisically fit , brand is not critical .

    If the coil voltage , line voltage , amperage , is the same . If there is room to fit , I like to go up at least 1 size in amperage .

    ( Note , for HVAC , coil voltage is usually 24 VAC . )

    Are you sure your existing contractor lists the FLA at 35? That doesn’t seem right when looking at the rest of the specs you listed for that contractor.
