Fuse XMM65 sides

Brackets/Sides for solar panel breakers

12v solar circuit should be protected by a fuse or a circuit breaker. You need at least three breakers. However the breakers are designed to be installed into a special enclosure. In a case of 12v solar system you can have stand alone breaker by using a designed cover brackets.
XMM65 and TOB1Z are identical breakers. The breaker cover has left and right brackets. The top four holes (to have an access for the screwdriver) are covered by screws or plugs. When printing the plugs do adjust the infill percentage settings close to 100%.
Left and right brackets are different. To connect the brackets together please use 3x40 mm bolts.
Safety note: even 12 v can be dangerous. This housing is designed to be used by a responsible and knowledgeable person. It is your responsibility to work safe with 12 volt equipment. I wouldn't accept any of your problems with wrong wiring, etc.
