Voltage level of air blast cct breaker
The voltage level of an air blast circuit breaker (ABC) depends on the specific design and application. However, here are some general guidelines:
- Low-voltage air blast circuit breakers: These are typically used for applications up to 600 volts (V) and are designed to interrupt currents up to 100 amperes (A).
- Medium-voltage air blast circuit breakers: These are used for applications up to 35 kilovolts (kV) and are designed to interrupt currents up to 5,000 amperes (A).
- High-voltage air blast circuit breakers: These are used for applications up to 72.5 kV and are designed to interrupt currents up to 20,000 amperes (A).
Some common voltage ratings for air blast circuit breakers include:
- 12 kV
- 24 kV
- 36 kV
- 42 kV
- 50 kV
- 72.5 kV
It's important to note that the voltage rating of an air blast circuit breaker is not the same as the maximum voltage that it can withstand. The maximum voltage that an air blast circuit breaker can withstand is typically referred to as the "withstand voltage" or "dielectric strength".
In general, air blast circuit breakers are designed to operate at a specific voltage range, and exceeding this range can result in reduced performance, increased wear and tear, or even damage to the breaker. It's important to ensure that the air blast circuit breaker is properly rated for the specific application and voltage level.
