RE: dc motor protection
I'd use a Battery Disconnecting contactor or a fuse. Bear in mind the allowances made for the motor's inrush current!
@ 24V, a 2.2KW motor may have a running current of several hundreds of amps. The inrush will likely to be between 4 and 7 times this value, but the duration (inrush) depends upon along it takes for the motor to get up to speed.
Best regards,
Lakey.
