These breakers from MidNite Solar break their rated amperage load at 600 DC volts repeatedly and with no damage. They can be used in MidNite Solar E-Panels, Combiner Boxes, DC Disconnect Enclosures, and Baby Boxes. They're standard DIN rail mount and fit nearly all array combiners, including Outback Power's.
These DIN rail mount breakers' Remote Trip (RT) feature allows them to work with Midnite's Battery Disconnect Module (MNBDM) and Rapid Shutdown System. They have been evaluated by ETL to 600VDC and are listed for the U.S. and Canada when used in a MidNite enclosure.
Always use a properly sized breaker for disconnecting.
Note: If using the Birdhouse for just shutting down a battery-based system breaker without a combiner, you must use the MNFX-CABLE faux cable (available separately on the "Accessories" tab).
