 Product Name: DZ20Y-100T transparent molded case circuit breaker 
 Scope of application: DZ20 series of clear plastic case circuit breaker (hereinafter referred to as "circuit breakers") applies to AC 50Hz (or 60Hz), rated current to 100A, rated insulation voltage 690V, rated working voltage of 380 (400) V and the following distribution lines as the distribution of power and lines and power supply overload, short circuit and under voltage protection. Where Y, and J, G-type rated current 225A and below, and Y 400A and below the circuit breaker can also be used as motor protection, under normal circumstances can be, respectively, as the line frequency conversion and motor infrequent start. 


 Products comply with GB 14048.2, GB of 14048.4 and IEC 60947-2, IEC 60947-4 standard. Normal operating conditions and installation conditions 
 1, the upper limit of the ambient air temperature does not exceed +40 ℃, the lower limit of not less than -5 ° C, and 24h, the average temperature does not exceed +35 ° C; 
 Note 1: the lower limit value of -10 ° C or -25 ° C, working conditions, users are required when ordering factory affirm; 
 Note 2: The upper limit of more than +40 ° C or lower limit of less than -25 ° C conditions, the user should consult with the manufacturer. 
 2, the installation site altitude does not exceed 2000m; 
 No more than 50%, atmospheric relative humidity in the ambient air temperature of +40 ℃, at a lower temperature allows a higher relative humidity, for example, up to 90% at +20 ° C, due to temperature changes to produce the occasional condensation should take appropriate measures; 
 4, the level of contamination: 3; 
 5, Installation category: the main circuit breaker III, the control circuit and auxiliary circuits for Class Ⅱ. 

 Structural characteristics of 
 This series circuit breaker is a Y-shaped-based products, consists of four parts of the shell of transparent insulation, operating mechanism, contact system and release. Breaker operating mechanism to make contact fast closing and breaking the "together", "minute", to distinguish the location of the "Rings" and "free trip" to the handle position. 
 Type C, type J and G-type circuit breaker is derived on the basis of Y-type products designed (except for C-type 160A). J-type circuit breaker is Y-shaped circuit breaker contacts to carry out structural improvements to make in the short-circuit condition, prior to agency action, the moving contacts quickly denounced open to achieve the purpose of improving the breaking capacity. 
 G-type circuit breaker is in the Bottom of the Y-type circuit breakers series of a parallel conductor repulsion limiting the contact system, the system longer than J-type repulsion contact, disconnect the distance, so they can more quickly and limiting; In the case of normal disconnect is closed and the trip short circuit tuning range of values ??of protection action by the Y-shaped circuit breaker. Once the current or large short-circuit current in the network, the series repulsion limiting contact by the electric power quickly denounced open, the introduction of the arc and limiting. Denounced open the process of contact, the release action of the circuit breaker operating mechanism of Y-type contact breaking. Repulsion limiting the contact due to the reduction or disappearance of the current back to its original state. 
 The C-type circuit breakers to meet the purposes of protection of 630kVA and below in the transformer grid distribution, through the selection of economic materials and simplifying the structure and improvement of process, to achieve better economic results.
