DZ47SD Dual Power Circuit Breaker

1、 The DZ47SD-63 series small dual power circuit breaker 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 DZ47-63 small circuit breaker, that is, when one circuit breaker is closed, the other circuit breaker can only remain in the open state, realizing protection functions such as line switching. Our company's independently developed dual power circuit breaker 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. The DZ47SD-63 dual power circuit breaker product complies with GB10963 and IEC60898 standards. 2、 Model and specifications

3、 Structural characteristics

DZ47SD-63Dual power circuit breakerComposed of a casing, operating mechanism, thermal release, electromagnetic release contact system, arc extinguishing system, etc., it has overload and short circuit protection functions. The unique structure design enables the product to have a short circuit capacity of 6KA and a mechanical life of over 20000 times. The installation guide rail is made of TH35-7.5 standard steel and has the following characteristics: it has added interlocking function, which means that when one side of the circuit breaker is closed, the other side of the circuit breaker can only remain in the open state, realizing protection functions such as line switching. The operation is comfortable, and the power supply is in and out, which conforms to the characteristics of power supply incoming and outgoing, and is easy to install.
DZ47SD-63Dual power circuit breakerDivided into 1P+1P, 1P circuit breaker; 2P+2P, 2P circuit breaker; 3P+3P, 3P circuit breaker; 4P+4P, 4P circuit breaker;
