Circuit breakers mainly are categorized based on application as per voltage.
1. Low Voltage Circuit Breaker
Low-voltage circuit breakers are typically used in applications such as lighting circuits, motor control centers, feeder circuits, and any application in which electrical power needs to be turned on and off and overcurrent protection is required.
2. Medium Voltage Circuit Breakers
Medium voltage breakers are designed to be operated electrically by a closing solenoid or a stored energy mechanism. Manual operation is used primarily for breaker maintenance.
3. HIGH-VOLTAGE CIRCUIT BREAKERS
High-voltage circuit breakers are mechanical switching devices that connect and break current circuits (operating currents and fault currents) and carry the nominal current in the closed position.
