help with contactor diagram

markymark2406 · 23 Sep 2010

Hopefully you can see my picture as this is the 1st time i have uploaded one.

I have 2 contacters side by side which control x2 3 phase pumps they are Square D (Telemecanique) the small ones on the front are code LA1KN11 AND the overloads are LR2K0310 not sure what the main contactor is.

all i need is a circuit diagramme i have taken a look on line with little success.

As Lectrician said, it's wired funny!
Whaat exactly are you trying to do?

Hi

datasheet can be found here, connections are at the bottom of the pdf
you also have an auxillary contact block (your LA1KN11's) fitted on each of the contactors that are using the NC contact, this is basically opening when the contacts on the main contactor are closing. without more info its not really possible to say what its purpose is but from the photo looks as if its probably an interlink curcuit preventing both pumps operating at the same time but again more info req

It's the markings which confused me like would I connect a push button switch which is set at normally closed (NC) to ????

what do you want the button to do?
