Pump starting using a timeswitch.

[AllanB]

I built a swimming pool 8 years ago and wired a 550w (3/4hp) pump to start on a 13amp timeswitch. Now the pump starting current I think is around 12 amps, anyway my 3rd timeswitch has just packed up. So my guess I need some sort of starter contactor, any advice what exactly I need, that hopefully I can order on Lazada?

 

Thanks

Control the coil with your time switch. Put both contacts in parallel in the live to the pump and it should last forever.

Thanks Crossy, Since I have to buy a new timeswitch, will this do the job?

Should do the trick, for a few years anyway.

 

The relay is probably replaceable in the event it fails anyway.

You are a gentleman Crossy and there aren't many of us left.

Hey Crossy, if AllanB puts in a contactor in, wouldn't it be better to put in a thermal overload with the contactor? Just a question between gentlemen.

On a 3/4 horse pump, I wouldn't bother although it would certainly do no harm.

 

We have 3HP irrigation pump which is direct on-line start on a simple contactor, no issues thus far.

Sorry for another question. What is the criteria for installing a thermal overload with a contactor?
