Introduction

The BR-DC175 and BR-DC250 are the same DC breakers installed in the MP

(Magnum Panel) and MMP (Mini Magnum Panel) system enclosures, and in-

cluded 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 were speciﬁ cally designed and tested to

work with Magnum inverters to provide the delay time needed to minimize

nuisance breaker tripping.

Depending on the part number, the circuit breaker is either a 175 amp (PN:

BR-DC175) or a 250 amp (PN: BR-DC250), high interruption capacity, mag-

netic-hydraulic, DC circuit breaker. These breakers have front-accessible con-

nections, each provided with a 3/8-16 captive nut. Each breaker includes two

3/8-16 Hex head bolts with washers, and a back mount kit for installing this

breaker inside MP enclosures. This kit consists of two mounting straps and two

#10-32 x 3.5” Torx screws to attach the DC breaker to a mounting panel.

CAUTION: These breakers must be mounted in a vertical position

to meet the speciﬁ ed trip current and trip delay curve.
