Hitachi 371468 Soft Start C10Rj Part

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.

Works great on my DeWalt 8 1/4" table saw. No more jarring start-ups, especially with my Ridge Carbide box joint blades.

Works great installed on my dewalt table saw. Nice softer start.

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.

Works great on my Harbor Freight Hercules Table Saw. I hope this photo will help someone hooking it up. It starts better than the no name brand. No more tripping of the breaker in the garage. Blue to white (add jumper or splice}. Brown to switch, black to motor.

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.

Like others, my Dewalt Miter saw would regularly trip my 20A breaker on startup - most likely due to a high rush-current. Once I figured out the wiring, the install was simple. On my saw, the 'trigger' unit has 4 wires connected to it. Black and blue on the left, red and yellow on the right. The black wire is the power to the motor. I disconnected this black wire from the switch, and connected the slow-start module in between -- the brown wire going to the switch/trigger, and the black wire to the motor wire we just disconnected. Finally, the blue wire on the module connects to the clump of white wires on the saw. I attached the module to the underside of the handle. I drilled a small hole for the wires to run into the handle, and used an existing, unused hole on the bottom as the screw hole to attach the module. I did have to extend the wire on the module so that it had enough length to reach the switch/trigger connection.

We've used these successfully on small window air conditioners to reduce start-up load. Then they don't overload our solar inverters on start-up.

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.
