I'm still not getting the idea of the icecube relay being at fault. It never sees the load of the motor, and it draws from a controller that would cut off its power if it were in any way an overload.

You're right; suspect the 24V transformer at this point, will post pictures this PM.

If you feed the pump relay directly with 24VAC, and leave the controller out of it, you may learn more. (assuming it is a relay with a 24VAC coil)

i think you may have eliminated the controller when you swapped it out for another, the transformer reads 26vac constant and the pump is working without the cube installed.

i wonder if the cube itself or the wiring to or from the cube is compatable as installed.

can you post a link to the PSR and the cube?

I don't see either a controller or a cube relay as even touching the 40-amp pump circuit. Apply power to the pump relay coil directly, and see if the pump keeps running.

TECO has a website, but "model 130674" doesn't scan. They have a DPA 2040 relay with a 7.5 HP rating for single-phase 240VAC

Here's the problem; the controler is wired into the same 40 amp breaker as the motor

Draw on the Baldor is just over 36 amps +10% gets me to 39.6 max load, this combined with the controller is apparently enough to trip the breaker.

The pump station is in a remote location, pulling an additional line is too costly; I'm thinking of having the electrician replace the breaker with a 50 amp and setting the relay to trip @40 amps. Or I could suspect the breaker is bad and replace it with a new 40amp and pi$$ away some more time. The controler, well eh, they are cheap.

I got the model # from Palm Beach Electric Motor who sold the unit. I've been busting a gut looking for some specs on it.

Was that TecoWestinghouse?

Does the controller have a choice of input voltage? Changing it to 240 from 120 would cut the current draw in half. You may not have the luxury of changing to a 50-amp breaker, depending on the wiring.

TECO is Chinese, so far as I can tell - it looks like you are running a motor that should have a higher ampacity circuit. Maybe someone bumped up from 5 HP
