Circuit Breakers - Automotive. Automotive circuit breakers provide a resetable and reusable alternative over standard fuses for circuit protection, and can altogether replace fuses and fusable links in most applications.
Circuit breakers are rated for a certain maximum current and will trip if that current is exceeded. This is to prevent electrical discharge and a possible fire from short circuits or faulty wiring. Because breakers are re-useable, the modern electrical panel is an improvement over the fuse boxes in older homes.
