The highest load has been while trying to trip it with the largest diameter rope-wrap on the drum, and skidding the tires pulling up hill -- see last paragraph of post#1 for details. Other than that, so far this winch has only been used to pull fallen trees, and it hasn't tripped. The manufacturers inverse time graph for the 200A breaker is saying ~20 seconds at 400 amps. My winch is rated at 420 FLA (full load amps), but I think it's very rare to get a winch motor to actually draw full rated amps because of the voltage drop with the typical battery/alternator setup (as voltage goes down, amps go down).

What's the FLA on your winch? When you get yours installed, it would be great if you report back after trying it out.

 

I don't know what FLA is. Full Load Amps? Page 17 here shows 452amps max draw: https://www.warn.com/fire_rescue/ass...e_Cat_2013.pdf


This is my winch (I bought and installed it new about 6 years ago):



I believe this is the parts list for my Winch: http://www.warn.com/truck/Replacemen...srrpl9.5Ti.pdf

 

Yep, FLA is Full Load Amps. I think its actually 425 amps for your 9.5Ti. Here's a couple links I dug up:

WARN 67550 - WARN 9.5ti Thermometric Self-Recovery Winch - Quadratec

Nice winch, very similar to mine. The breaker you ordered is the same as mine too. I think the odds of you liking the way it works are good.

 

Yup, that's my baby. It's been good to me. I forgot that it has temp feedback. It's got one very cool feature: it winds in even with gears unlocked so that when the cable gets all the way in, it just spins free without destroying roller. Handy!

I bought the same breaker on purpose. I'll let you know how it works.

they used 500 amp fuses for each winch.

 

Relatively new to this....... is it a common occurrence for winch motors to get stuck running? I assume if it happens it is likely due to a solenoid failure rather an internal short in the winch motor? I have had a winch on for about a year now and have heard mixed opinions as to whether the increased number of connections and failure points you add with a cutoff switch or breaker is really worth it.

I didn't know you could install something for this cheap though...... may make the decision a little easier.

 

Stuck running is not common. Shorted wiring (which can cause a fire-battery meltdown) is rare as well.

You're right about a solenoid sticking, but it could be as simple as the switch/remote shorting out and energizing a solenoid. An internal short in the motor could draw a lot of amps and perhaps weld the contacts in the solenoid. In this case, a circuit breaker or fuse would interrupt the circuit based on over-current.

As to the risk/reward, a potential nuisance trip is about it for downside risk. And if there was a complete failure, a few minutes with a wrench can re-wire it directly to the battery.

The circuit breaker/switch (see post #1) is marine rated (IP66) and the contacts are capable of interrupting 5000 amps. The terminals are like whats on a on starter motor, not much to go wrong.

 

I installed a Warn Power Interrupt switch. Here's my install video.

Nice quality video

 

That is quite the electrical setup, it looked like three 500 amp fuses -- presumably for three winches. The video really shows off the quality workmanship.

If I had a bigger winch (more amperage), or the breaker hadn't worked out, I'd use an AMG or ANL fuse as well.
