Hitachi 371468 Soft Start C10Rj Part | Soft Start Module | Electronic Control Component | OEM Replacement Part | Controlled Motor Startup | Electrical Assembly

I ordered a couple of these Hitachi Soft Start modules to retrofit my table saw and shop vac. They're rated for 15A which is more than enough for my tools and unlike cheaply build no-name modules it has heavy 16ga wire and a heat sink to dissipate the heat generated from being in-line with the motor. Wiring the module into my saw was really easy - I just added some spade connectors and a Y adapter on neutral so I could insert it into the existing wiring without modifying the saw. The saw still starts pretty fast, much faster than the no-name module I had to use for my miter saw, but slower and quieter than it used to be. Best of all this authentic Hitachi part was less expensive than the no-name modules! Honestly I would have preferred to use one of these in my miter saw also but with the heat sink it was too big to fit.

good value, has a heat sink, adjustable, arrived fast, has simple schematic on the back, worked great. My chop saw recently started tripping the 15 Amp AF breaker the garage shares with some bedrooms. I couldn't tell if it was tripping on amps or arcs. New brushes didn't help. This looked small enough to fit in my chop saw handle but I wish I hadn't tried to put it into the handle, kind of a nightmare to get the handle off, then inside the handle I would have no access to the potentiometer, plus ultimately wouldn't fit. But if I'd been thinking harder at the beginning I never would have tried to take the handle off. Has EU brown/blue color code so I looked that up:blue=neutral. For some 12VDC RV project I bought an extension cord because that was the lowest $/ft 16 AWG jacketed cable. This soft-start module plus the plug form the cord and some parts I had around worked great to wire up a soft-start outlet box. Solved the problem also, saw starts/works great in the original outlet. I seem to be able to tell the amount of soft start increases as the pot is turned counterclockwise. Good luck.

Good deal, works great.

Hitachi 371468 Soft Start C10Rj Worth the money. Easy install. Added this Soft Start device to a Dewalt 7491 table saw. Works GREAT...

I had a Bauer brand Harbor Freight chop saw. It worked for a few months, and then started tripping my 20amp breaker everytime I pulled the trigger. I was right in the middle of a big project and so I tried many different outlets and circuits and sure enough it kept tripping any of the 20A breakers. The only way I could finish the project was to use a long and really too small of an extension cord. I'm assuming it acted like a big resistor and could get the saw started softer. When I was done with the project, I took the saw back to Harbor Freight and explained the problem and they gave me a brand new one. Well, this one was even worse. Even with no blade on it at all, it would trip the breaker on start up. I started digging and found this fix for other saws, so I decided to try it on my Bauer. It works! See pics of how I got it in there. A little trimming with a dremel and it fits in there very snugly. Easy to wire. Cut the wire that goes from the switch to the motor. Hook the brown wire to the wire coming from the switch. Hook the black wire to the wire going to the motor. Hook the blue wire to neutral. Easy. I spent more time trying to get it to fit and look nice than I did anything else. Motor starts smooth now!

Soft Start Did Not Work As Described. I connected this soft starter to a 1/2 HP, 10A (run), induction motor. The work load is only about 1/3 of it's full load capacity, 3.8A. Using two clamp on amp meters I checked peak amps before and after connecting the soft-start. I ran about 10 different tests. There was no significant difference between using it and not using it. I also connected my shop-vac to it and checked the peak amps before and after. No significant difference. I couldn't even hear a difference in the sound of the shop-vac when it started. I also checked an incandescent lamp to see if I could see a ramp in the brightness of the bulb when it was turned on, and I couldn't tell a difference. BTW, I used two peak capture amp meters, and I tested two different soft-start modules. I triple checked my wiring. Finally, I discovered the built-in Potentiometer and turned it 1/2 turn CCW to increase the on-delay time and it worked.

Relatively straightforward to install electrically. The other reviews gave enough directions. The issues are just how to physically include the device, but removing a bit of plastic for the heatsink to pop out was the only thing i needed to do. The functionality is a clear removal of that first big 'thunk' as the 12" blade spins up. It is still a quick start, but quick as in 1 second, not quick as in hell for leather. Took about 30 minutes to add it until it was all enclosed again.

It was easy to install and fits inside the switch box. I really appreciate the smooth start. The biggest difference for me was if I left my cross cut slide or some other jig and place it used to be that when I turned on the saw the jitter would mess up my cut line now with the soft start the blade move so smooth that doesn’t even rattle sideways and affect the kerf. Of course your blade shouldn’t be in a kerf when it starts up, but reality be realiting… Besides that the start up used to be so sudden, it was almost scary as a sound to those around and you wondered if it was harsh on the components This is just so much smoother

Me gustó que trae ajuste de arranque, anteriormente tenía uno chino y no me gustaba el arranque tan lento, muy buena compra !

Very well made soft start module, nice thick cables. I particularly liked the external heat sink, and the adjustable pot which allowed for different levels of soft starting. Very easy to wire up also.

Installed on a Ridgid table saw and works awesome. So much quieter when saw is turned on. Does not scare the crap out of me anymore. Worth it and recommended. You will love it.

My saw does not come with a soft start and I some online material that says you can use this part to add it in. Happy to report that it works perfectly but it made a massive difference. The table saw previously would cause my garage lights to flick when i turned I turned it on as its a pretty aggressive 0-hero blast off mode start speed. After wiring this up at the switch its amazing. At the slowest setting its probably 1.5ish seconds to ramp up and when I turn the saw on the garage lights don't flick in the slightest.

Me gusta el artículo comprado porque ahora mi sierra de banco inicia a trabajar más suave y sin el arranque estruendoso con el que viene de fabrica, Gracias, Amazon.
