Line voltage (resistive load) T-stat to switch low voltage coil (inductive load) ?

[Mikros]

Hi, I'm thinking this will work ok, but the heater(s) I am switching are in a pump station where failure is a bad thing.

I have a couple of 3-phase 480v heaters 5kw, and they have their own switching built in. They have a contactor (12v coil) and a control power transformer (12v)


The heaters have a j-box for the 3-phase line power to be tied in, and also have two low voltage leads brought out that when closed, close the contactor and turn on the heater.

I'm thinking to put those low voltage leads on a single pole line-voltage heating stat. The heating stat says it is for resistive loads, and a contactor coil is inductive.

The two heaters will get separate stats.


Any opinions on this possibly being a bad idea? Thanks! Jeff (EDIT: DOH! I MEANT TO PUT THIS IN THE GENERAL ELECTRICAL FORUM SECTION)

You'll be fine.

What Hal said. Yes, the coil is an inductive load, but at the milliamps it's likely drawing the T-stat won't care.

Thanks guys, I think I will run with the plan. I get nervous about details once in a while.
