I have 3 Thermarator's, each is 460 volts 3 phase the FLA is 12.43 amps.
do I need each unit on its own disconnect ( breaker ), or can I have all
3 on one disconnect. to be code complaint, ?? I am in industrial manufacturer
Thank you. for any and all information.

Do you mean Thermalator? How will they be connected (hard-wired, cord and cap)?

I'd be kinda surprised if you could gang three units on one breaker and it certainly wouldn't make maintenance/service any easier. You'd also have to wire them all with 45-50 amp wire to match the breaker rating.

Does the manufacturer say anything about this (check the ratings plate and the install instructions)?

This is not, in my opinion, a question that a qualified electrician would need to ask. Please hire a licensed electrician.
