SMN11-N series miniature circuit breaker, mainly used for AC 50 Hz or 60 Hz, rated working voltage 230/400 V,rated current up to 63 A and below, rated operation short-circuit breaking capacity not exceeding to 4500 A,as overload. For short circuit protection, it can also be used for infrequent on/off operation and conversion of lines. The interior adopts a bipolar structure design, in which one pole is protected, and one pole is unprotected and the bipolar structure simultaneously closed and disconnected, thereby solving the hidden danger of using only one pole switch at the single-phase end of the residential house.
