What is a Circuit Breaker?
The circuit breaker is a protective device which is used in many places such as industries, home, etc to protect the circuit from short circuit and overload conditions. If we don’t use the circuit breaker then when any fault occurs the wire will burn.
What is an Isolator?
The isolator is an electrical device that is used in substations, generating stations, etc to isolate the circuit while doing any repair or maintenance.

Difference between isolator and circuit breaker
| SI.No | Circuit Breaker | Isolator |
| 01 | Circuit breaker is used to interrupt the fault current (short circuit or overload) as well as normal current | The isolator is not designed to interrupt any current. |
| 02 | The circuit breaker can be operated in both the cases when there is a load and no-load | The isolator is to be operated when there is no load. |
| 03 | It can operate automatically, and also it can be operated manually. | The isolator can not be operated automatically, it is to be operated manually. |
| 04 | The circuit breaker protects the circuit from fault. | The isolator is used to disconnect the parts of the system that will help the workers for maintenance. |
| 05 | The circuit breaker is provided with an insulating medium like oil, vacuum, gas, etc. | The isolator does not require any insulating medium. |
These are the main differences between the isolator and circuit breaker. I hope this article may help you all a lot.Â
