20/02/2021Compare the advantages and disadvantages of Solid State Circuit breakers with other circuit breakers briefly: While solid state circuit breakers can achieve substantially faster interruption speed compared to conventional electro mechanical based circuit breakers, one major drawback of solid state breakers is their high on state losses. With contact resistance as small as a few micro ohms, electro mechanical contacts in classical circuit breakers introduce negligible on state losses.
