Types of High Voltage Circuit Breakers | Explained
Axial blast circuit breakers are well-suited for Extra High Voltage (EHV) and Ultra High Voltage (UHV) applications. In this type of circuit breaker, a high-pressure air blast is directed longitudinally, aligning with the arc. To mitigate transient over-voltages, resistance switching is implemented.

Guide to Circuit Breaker Lockout Devices | Total Lockout USA
Another way to determine what lockout device to use is by looking at the voltage of the circuit breaker. Circuit breakers can range from 120V to 600V, and there are devices that can work with each voltage range. For example, oversized lockout devices are designed to work with voltages of 480V and 600V, while snap-on devices work well with 120V [6].
