Can anyone recommend an UL approved disconnect, for service entrance application, suitable to operate on a 650VDC bus? Need sizes from 50A up to 400A. I also look for UL approved fuse-disconnector or switch-disconnector-fuse (for NH type IEC/DIN fuses), for service entrance application, suitable to operate on a 650VDC bus. Need sizes from 50 up to 400 Amps.

Tanks very much.

Hi , You can check if what you need is made by ABB. The site address is http://www.abb.com.
You can choose product group, Low Voltage Products/Switchgear.

For fuses, you can check with bussman, http://www.bussman.com site.

Hope this information is useful to you.

Just out of curiousity, what possible application could require a service entry rating at 650VDC?

It's a common DC bus for VFD's. Rectifier panel and VFD's line-up are located in different rooms; need to disconnect the line-up 650VDC incoming line.
