Automobile electrical circuit breaker with resettable switch. Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive ...
Littelfuse, Inc. is an American electronics manufacturing company headquartered in Chicago, Illinois. [2] [3] The company primarily produces circuit protection products but also manufactures a variety of switches, automotive sensors and, through its subsidiary Zilog, microprocessors. [3] [4] Littelfuse was founded in 1927. In addition to its ...
Resettable fuses - PolySwitch devices. A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits.
As the removable plug was returned to the socket, the wires were reeled back into it. The circuit was closed either by pressing a button or removing the igniter from its socket. [4] The modern "automatic" removable automotive V-Coil lighter was developed by Casco in 1956, [6] for which it received U.S. patent 2,959,664, issued in 1960.
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire.
During those 1.5 cycles, other separate circuits can see voltage dips or blinks until the affected circuit opens to stop the fault current. Automatically closing the breaker after it has tripped and stayed open for a brief amount of time, usually after 1 to 5 seconds, is a standard procedure. [5]
