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.
All circuit breakers are overcurrent protection devices, which are used to disconnect a circuit in the event of a prolonged overload current or a short-circuit current. An aiâ¦r circuit breaker is one of many types of high-voltage circuit breaker. It uses a blast of compressed air to extinguish the arc formed when its main contacts open. In some cases, air pressure is also used to operate the mechanism that opens and closes the main contacts. 4 people found this useful.
