I have an application where I am using a 24V DC motor to drive a ball screw. If someone isn't paying attention and they hit the mechanical stop on the ball screw, the current is going to spike to about 200 Amps. The normal running current is about 35 amps, and the max current is 60 amps.
I'd like to put a fuse between the motor controller and the motor. If possible, I'd like it to be a resetable fuse like a circuit breaker. I'm currently using an automotive fuse, but after looking at the data sheet, this 60A fuse will need to see 200A for 5 seconds before it breaks. I'd like the fuse to blow as soon as the current exceeds 60 amps, but I can't seem to find what I'm looking for. I'm not an electrical engineer so maybe I don't know enough about fuses and how to read the Time-Current Characteristic Curves. Hopefully you guys can help me.
