I measured the 'initial' current draw at 160 amp two weeks ago. This was with the air temp @ ~ 40F. This was with a FLUKE Clamp Meter and it took a couple seconds from key on to check the meter.

Splitting the GP load across two relays would definitely extend their lifes as the current thru each would be halved...other than the mounting issues, seems straight forward.

Another idea would be to add a suppressor circuit across the contacts, something as simple as an R-C filter....just food for thought.

 

Bill, that's for the 70-902=copper contacts.
586-902=silver

 

My bad. I looked at 70 series not the 586 series.

Hi All!

Just found this very good thread and had a question - would a Stancor 586-903 Relay rated at 16 VDC help extend the life of the Relay?

Thanks - Steve

 

No, it would have trouble energizing if at all. It's not the coil DC rating but the contacts current rating that is important.

 

Thanks Hussler, appreciate the Reply - Happy Holidays!

 

Is the 16VDC the max volts the relay can handle so presumably it will be more robust than the 902 which is rated at 14 iirc?

 

I think Hussler's Reply answers your question … but I am not very proficient with electrics.
