Re: [RE-wrenches] Lorentz Sub Pump

[Kent Osterberg]

David, Sq D doesn't have them UL listed for it but they self certify the 10 to 30 amp 2-pole breakers for 125 volts dc.  Problem is: if you need a UL listing, you are stuck at 48 volts.

David Katz wrote: Allan, Are you running 100+ volts DC through a Square D breaker?  They are not rated for anything above 48VDC.  Midnite Solar makes a manual transfer switch that can be fitted with 150 VDC breakers.  That may be a better choice.
