    OK, you can stop your search for a mosfet/transistor.

    You will all most certainly be better off using a simple mechanical switch to interrupt the signal source to the speed controller.

    If you will simply post a link to the ESC (Electronic Speed Controller) you are using (and if the signal source to the ESC is NOT embedded with the ESC, then a link to whatever device you are using as an input signal to the ESC) , I feel confident someone here will be able to help you achieve a satisfactory means to disable the motor w/o attempting to actively switch 3.6kW.

    Cheers!

    I think i over complicated it, i basically
    need a switch that can take on 60v and 60a..
    For that im looking for a mosfet as i thought its the best solution.

    You mean how did i know they dont work ?

    I am using this vesc.

    As far as i know, some vescs do have an enable input, i couldn't find any info for that with my vesc..

    As mentioned above, im using a vesc, your idea about the signal input switch is possible as the signal input isn't embedded.
    But im looking for that 3.6kw switch because i don't want anything connected to power when the switch is off.. i i have some regulators and leds on the board, so i figured the best way is to just place a mosfet on the main output from the battery, and just "kill" everything with one click.

    Im basically trying to copy one of these

    You don't need a dedicated enable input. Just interrupt the pwm signal and ensure that without an active pwm signal a the control input the motor controller is in the off state (e.g. by adding a pull-down resistor from the control input to 0V).

    If you don't want to buy one of these, why not simply use the transistors that are used in these: NVMFS5C628NL aas stated on the website you linked?

    Sorry for the long time to reply,

    That actually a great idea, unfortunately i could not find as a through hole, do you think it will be possible to solder it that way ?
