QO Breakers and Panels [RE-wrenches]

[Eric Smiley]

Airpax makes virtually identical breakers to Heineman.

Square D makes single pole, moulded case breakers with 125 Vdc ratings:
FA Series come in 240 Vac, 480 Vac and  600 Vac versions with 5, 7.5 and
10 kA IR ratings for DC respectively.
FH Series breakers have a 10 kA IR rating.

Price and availabliltity are another issue.

Similiarly Cutler Hammer makes 125 VDC rated breakers and so does
Siemens. However, check with the manufacturer first, as many of these
are intended for ungrounded DC  systems.
