The BR-DC175 and BR-DC250 are the same DC breakers installed in the MidNite and Magnum Panels system enclosures, and included with the MPX extensions. These breakers function as the inverter’s DC disconnect switch and can be used as the battery-to-inverter circuit protection in most installations. These breakers are specifically designed and tested to work with MidNite Solar and Magnum inverters to provide the delay time needed to minimize nuisance breaker tripping.
