In addition, the insulation is configured to provide effective control over electric fields around the used components, thereby minimizing any risk of internal arcing. Circuit breaker has to undergo power frequency withstand test, in which power frequency voltage is applied to the circuit breaker for 1 min. While switching back to back capacitor banks, inrush current is very high and hence there is a high possibility that the arc will restirke. Cloudflare Ray ID: 7a2b3a073fbaa529 If the M.2 SSD uses AHCI protocol, its read-write performance is same as that of SATA SSD.
