Molded case circuit breaker having improved arc resistant properties |
摘要 |
Molded case circuit breakers having increased short circuit current ratings contain a dual contact blade arm assembly and an arc shield wherein the operating mechanism is shielded from the arc blast which occurs during contact arcing. The arc blast shield consists of a trifurcated barrier interposed between the circuit breaker operating mechanism and the arc chute without interfering with the contact arm motion.
