I am putting together a design for a custom Electrical panel. The panel consists of mainly DC powered components (Sensors, Controllers). Components are to be mechanically positioned using a DIN rail.
Operating voltage of the DC circuit is 24V, and components in the circuit have maximum current ratings ranging from 1A to 3A
Adequate and proper protection is a major requirement in this project. Digging around for circuit breakers, i realized that the more common AC circuit breakers out there (In my geographic location) are not recommended to be used in DC circuits.
Further digging also revealed that these DC Circuit breakers are about 2 to 3 times the cost of their AC counterparts which is bummer as this has affected my projected costing.
Alternatives i read about include the use of fuses. This has its advantages and disadvantages too.
My question is, in my scenario what is the industry recommended way of providing protection in DC circuits.
