Hello, I'm looking for help selecting a drum switch for a motor and have a few questions about it.

Motor: WEG W22 single phase (cat ID 00318ES1B184TC-W22) - 3 HP, 115/208-230 V

When looking into drum switches, most have a HP rating of 1.5 @ 115V and 3 @ 230V. In my case, I will be plugging this motor/switch into a typical 120V outlet. The data sheet for the motor gives a output of 3 HP with a rated voltage of 115/208-230 V. Should I assume the 3 HP output from the data sheet is at 230V and less for 115V? Or should I be looking for a drum switch rated for 3 HP @ 115V? Would there be any issue with drum switch with a lower HP rating than motor output?

Don't want motor starter and contactor instead drum switch?

Sorry, not completely familiar but do you have a link to a starter/contractor you could share?

I was planning to couple this motor to a gearbox/oil pump to transfer oil in/out of barrels and was envisioning wiring in a drum switch to control the direction. If you believe a starter/contractor may be a better route, please advise, I’m just not too familiar with setting those up or for my application.

Something like this, and you would need an overload block if the motor does not have overload protection built in. You would also need a control switch station.

Drum switch 3 hp, 115V may not available in market
Instead, use two magnetic contactors, forward and reversing, low rated drum switch in contactors coils circuits
Provide ocpd upstream
