Photovoltaic solar dc miniature circuit breaker

Application

  DC1200V/NC4P125A DC Miniature Circuit Breaker, apply to rating current 63A or less, Direct current rating voltage 250V and 440V.  It is mainly used for the overloading and short circuit protection in DC distribution system equipment and electric equipment. It can be widely used in electric, post, traffic, mining enterprise and different kinds of fields. In present China, our products in the case grade rating voltage is highest compared to the same products.

Products according IEC60947,GB14048.2 standard.

 

Characteristic

  DC1200V/NC4P125A DC circuit breaker is made up of case, operation mechanism, thermal overloading trip, electromagnetic trip contact system, arc system etc. It has overloading and short circuit protection, unique-design structure and strong permanent magnetism arc system make the product has 6KA short circuit capability. Long mechanical life over 20000 times and beautiful shape. It can be connected with din rail named TH35-7.5 standard stainless type and has the below personality: the handle is designed on the top of the front, people will feel safe and comfortable when operating. When connecting, pay attention to “+, -“ poles; The power goes in from the top and comes out from the underside which is applied with power entrance character. Convenient for installation and saving cables. It is used for 440V circuit 3 poles circuit breaker to connect front loop for two poles serial connection
