Hi all, 

I have a device which we are operating using 3 phase 208 VAC. 

I want to select a Circuit breaker to protect and control the device. I have selected 3RV2742-5ED10 for the application. 

I want to know if this CB can work properly at 208 VAC 3 phase. 

Alternatively I can also work with 3RV2742-5FD10 and select a right fuse. 

Thank you. 

Hello,

Which device you want to protect?

How much is the rated/nominal current?
