Thanks for your question Dale.
I've tracked down the following additional information regarding this Middleby Marshall 27381-0054 208/230 Volt Convection Oven Motor:
- 60 Hz
- AMB does not matter
The motor is designed to operate under extreme heat conditions for commercial kitchen use.
Please give a member of our Tundra Restaurant Supply team a call at 1-888-388-6372 if you'd like assistance finding a motor that will suit your needs.
