I purchased some contactors awhile back, and have no idea how to wire them up. Can anyone provide some assistance? These will be used to switch on/off my pumps. Thanks!

They were purchased from AutomationDirect, but it looks like they don't carry the CN-6 anymore. FactoryMation link

Thanks for the link. I've found similiar manuals, but nothing on wiring, or at least - that I can tell. I'm also concerned, from the specs it looks like this only supports 3 phase? Maybe these contactors won't work? Crap.

I'd be willing to bet it'll work just fine.

Take a multi-meter and close the contacts then check each contact for continuity.

Looks like L1 and T1 go together, L2 and T2 go together, and L3 and T3 go together.

Looks like there's a manual switch too. 1=On, 0=Off. Nice feature.

I just don't know where the coil connections are. Probably A1 and A2 if not anywhere else.

Good Luck!

Yeah, what stlbeer said. Generally, L terminals are the line side input and T terminals are the controlled load side. I would guess A1 & A2 are the coil terms and 13 & 14 is a set of pilot contacts with a much lower current rating than the main L1-3 contacts. Typically, these contacts for additional control / sequencing or indicator functions. The manual I/O tab is a handy visual indicator if the armature is pulled in magnetically and provides a means of manually operating it for test purposes.

Re: 3 phase: You don't need to use all 3 main contacts. Just as many as you need.

But those contactors are only rated at 20 amp (or am I reading that wrong) - what size element do you plan to use?

stlbeer and junkster hit it right on the nose for the wiring A1 A2 are coil and 13,14 are a NO auxiliary contact set. You will be just fine using this for your pumps and can run up to a 4500 watt element if you ever decide you want to.

So I wired this all up, and the control voltage (24VAC) isn't causing the contactor to 'kick over'. The manual switch works just fine. I tested the voltage over the A1/A2 connection and I'm getting 24VAC. I'm fairly certain they are rated at 24VAC to kick, any ideas?
