A second incident, the flash crash of May 6, 2010, saw the DJIA lose points, or over 9%, in just ten minutes. Prices recovered—or very nearly—before market close, but the failure of post-1987 circuit breakers to halt a fat-finger trade and the panic it caused led FINRA ​, the exchanges and the SEC to develop a new market-soothing regime. (The "fat-finger trade" theory, which posited that an inattentive trader had typed too many zeros and thus placed a gargantuan sell order, later proved false. London-based trader Navinder Singh Sarao is thought to have caused the crash through the use of spoofing algorithms, but his alleged role was not revealed until his arrest in April 2015, after the current circuit breakers were put in place.)

Let's have a discussion on electrical principle of circuit breaker .
The circuit breaker has to carry large rated or fault power. Due to this large power there is always dangerously high arcing between moving contacts and fixed contact during operation of circuit breaker. Again as we discussed earlier the arc in circuit breaker can be quenching safely if the dielectric strength between the current carrying contacts of circuit breaker increases rapidly during every current zero crossing of the alternating current. The dielectric strength of the media in between contacts can be increased in numbers of ways, like by compressing the ionized arcing media since compressing accelerates the deionization process of the media, by cooling the arcing media since cooling increase the resistance of arcing path or by replacing the ionized arcing media by fresh gasses. Hence a numbers of arc quenching processes should be involved in operation of circuit breaker. Types of Circuit Breaker According different criteria there are different types of circuit breaker . According to their arc quenching media the circuit breaker can be divided as-
