vfd-motor disconnect with early switch

vfd-motor disconnect with early switch

(OP)
I've Eng-Tip'd and googled and searched various vendor sites, but am not finding a suitable disconnect solution. I am using a 3HP 3ph 208v motor controlled by an appropriate VFD, and want to put a manual LOTO disconnect on the load side of the drive. I don't see anything manual with an auxilliary switch, 'early' or otherwise. Is this not a common practice?
I can probably get away with using an electrically actuated switch (contactor), but would prefer manual, and I don't need any bells or whistles (OLP, PLP, etc)...
Thanks

RE: vfd-motor disconnect with early switch

Haven't needed to look for one for years, but it used to be an available option on several lines of disconnect switches for the US market.

I agree with David. Same experience.

RE: vfd-motor disconnect with early switch

Nobody will have it built-in to the switch, but lots of people have the switch, then you can add a handle operated aux. contacts.

Go to page 23 of this brochure:

RE: vfd-motor disconnect with early switch

I don't think the switches in the previous Hubble link aren the ones you want. Try here instead.
