Choose the right circuit breaker for specific vibration environment

The resisitance levels of random sinusoidal vibrations are classified by a relative letter. The letter “A” corresponds to the lowest vibration perfomence, while “G” indicates the highest vibration tolerance. These letters are indicated on the circuit breaker as in the example below.
