Relay / Solenoid recommendations

Bob · Post by **Bob** » Thu Oct 06, 2005 4:16 pm

I'm looking for manufacturers and part numbers for continuous duty relays and/or solenoids.

I have a customer who wants to ignition-switch his entire lighting package. The install was designed around an 80 amp draw, but the actual draw is around 50 amps. To keep consistant, I'm looking or something that's rated at 80 amps, continuous duty.

I've looked at some of the TST products. They'll be out of the scope of this particular project, but I'm looking into them for the next install I do.

Input?

Bosch sells a 75A constant-duty SPST relay that's available from Tessco and others. I use them to switch my master busses with no trouble. Tessco part #53273, about $18 at Gold pricing.

I've gotten heavy duty solenoids from the four-wheel drive/truck accessory shop before. They are used on winches, so just ask them for a winch solenoid.

Code: Select all



Be careful with stuff like that.    Some of these parts people don't know what they're talking about.  I'd recommend that you cause the sales person to show you in the catalogue that this IS in FACT  a continuous duty solenoid.

(I sold that stuff for 15 years)

A hint--if  you pay less than about 20.00, it's probably a "starter"  relay.

Pollak, and NAPA,  as well as any "real" parts store, used to market them.   With the current  chain store attitude, it's anyone's guess.

Go visit a local car audio shop. They usually carry continuous duty relays in various ratings, one local shop here sells them up to 200amp models.

The local RV supply stores usually have continous duty relays on the shelf. They look like a starter relay but are all metal, no plastic body. Usually the price is bearable also.

i put a cole hersee #24143 in my truck for just that purpose. that model is 200A continuous duty, but if that's overkill for you they have others. local auto parts store liberated me of $49.65

Thanks guys. I don't trust the folks at AutoZone or Advance Auto to come up with part numbers for me. Unless you give them a specific vehicle and application, they're pretty well useless. I ended up with a starter solenoid a couple days ago that I'm going to have to take back.

I keep forgetting that there's a Grainger about 15 miles from me.

I have used the Bosch relays for a number of years. They work good.

A word of caution on what ever you end up using. Try to stay away from push on crimp connectors. they end up coming loose over time and will burn up the connection. I tend to try finding a relay with screw terminal connections. Never had a loose connection with this style. The crimp spade lugs work fine on the screw terminals on the relay.
