Protective devices for electric equipment and circuits act as survival kits. Because of the steadily increasing power being fed into transmission lines, these guardians must often respond faster to protect equipment and branch circuits. Suppliers provide a diverse selection of devices in order to handle the broad spectrum of traditional protection needs as well as innovative designs for newer applications with rapidly changing requirements.
Basically, the protection choice is magnetic circuit breakers—a class of protector where the breaking of the circuit is a function of current only. Although the value of and need for other devices, such as fuses and thermal breakers, when used correctly, serve useful functions, the major emphasis is on magnetic breakers, the electromagnetic circuit protectors which lend themselves to a great variety of ingenious devices.
Potential applications for magnetic circuit breakers include computers, microprocessors, and other solid-state system protection, remote controls, industrial automation and air-conditioning, variable speed drives and a myriad of other industrial equipment and systems.
