What are the three basic types of circuit protection devices?
There are two general categories of circuit protection: 1) Fuses 2) Electro-mechanical circuit breakers. Each has its advantages which will be discussed here. Fuses break down into three convenient categories —fast-blow, slow- blow, and semiconductor.
What are protection devices?
Protection devices are installed with the aims of protection of assets and ensuring continued supply of energy. Switchgear is a combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.
What are control circuit devices?
Circuit control devices are used to “turn on” and “turn off” current flow in an electrical circuit. Circuit control devices have many different shapes and sizes, but most circuit control devices are switches, solenoids or relays. A switch is the most common circuit control device.
What device controls current in a circuit?
The instrument which is used to control current in an electric circuit is rheostat.
What are the different types of protection devices?

What is protection circuit?
Circuit protection is the intentional installation of a “weak link” in an electrical circuit. This is a fuse or circuit breaker, referred to here as a circuit protection device or CPD.
Why circuit control is needed?
Circuit control devices allow you to turn the device on when it is needed and off when it is not needed. Some devices, like multimeters or televisions, require the selection of a specific function or circuit. A circuit control device makes possible the selection of the particular circuit you wish to use.
What are the different types of control devices?

What are control devices?
Control device means equipment, other than inherent process equipment that is used to destroy or remove a regulated pollutant prior to discharge to the atmosphere.
