1、 Scope of application

DZ47SD-125 series smallManual dual power switchIt is a new type of circuit breaker with interlocking mechanism independently developed by our company. This product adds interlocking function on the basis of the original DZ47-125 small circuit breaker, which means that when one side of the circuit breaker is closed, the other side of the circuit breaker can only remain disconnected, achieving protection functions such as line switching.
Our company's independently developed manual dual power switch has dual functions of overload and short circuit protection and line conversion. The product is designed reasonably, reliable, and has a beautiful and lightweight appearance. It is mainly used for overload and short circuit protection of switching and other control lines.
DZ47SD-125Manual dual power switchThe product complies with GB10963 and IEC60898 standards.
