This post is an addendum to the Cutler Hammer post from last week.
My research has yielded a bit more info, but not quite enough for me to be content.
CH 3 pole AC reversing push button switch No 9122H3A
* I found a label on inside of cover w/ a date a "Dec. 1947" Yikes!! It's old.
It also says...
Max HP Ratings Single Phase: 1 hp - 115v; 1.5 hp 230-575v
Max HP Ratings 3 Phase : 1.5 hp - 115v: 2 hp 230-575v
Now, I can't find any evidence of a control tranformer on the lathe. So I'm assuming this is/can be a FULL Voltage switch.
Secondly, JRaef stated in other post that I should be sure to confirm the current rating of the switch. This I have not been able to do.
But, would it be safe to assume that a typical 1.5 hp 3ph 220volt motor that draws 5.8 amps(this is on the motor data )plate would be safe to be controlled by this switch?
Is there a wide range of amperage draw among motors of this size?
Last night, I visited an electrical supply place in Laporte, IN on recommendation of some local guys who couldn't answer my questions. An older guy runs the place. I brought in my pictures/schematics asked my questions to guy at counter, no luck. He calls upstairs for the owner who comes down, listens to me and informs me that he'll sell me whatever I want but don't bother him or his people with questions they can't answer,"...that's what electricians are for."
Thanks, Paul
