The circuit breaker has overload and short circuit The circuit breaker and undervoltage protection function can protect the circuit and power equipment from damage. According to its rated limit short-circuit breaking capacity, it is divided into three types: L-type (standard type), M-type (higher breaking type), and H-type (high breaking type). This circuit breaker has the characteristics of small size, high breaking capacity, short flashover, and vibration resistance. The circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally). The circuit breaker has isolation function, and its corresponding symbol is: • - ∞CLASSIFICATIONThe circuit breaker meets the standards: 1EC60947-2, GB14048.21.1 According to the breaking capacity of the circuit breaker: a standard type (S type) B Higher type (H-type)1.2 According to the wiring method of the circuit breaker, it is divided into: a front wiring of the board, b rear wiring of the board, c plug-in type;1.3 Classification by operation method:Direct operation of a handle; B Rotate the handle for operation; • Electric operation;1.4 Divided by number of poles: two poles; Triple pole; quadrupole1.5 According to attachments: alarm contact, auxiliary contact, shunt release, undervoltage release;Model and its meaning1. Circuit breakers for power distribution do not have a code: protection motors are represented by 22. Handle direct operation without code: electric operation is represented by P; The rotating handle is represented by B;3. The maximum short-circuit breaking capacity of the technical rating can be divided into mountain type (standard type), M type (higher breaking type), and A type(High breaking type)4. According to the extreme of the product, it is divided into three poles and four poles. There are three types of neutral pole (N-pole) in quadrupole products;Type A: N-pole does not have an overcurrent release installed, but the N-pole is always connected and does not open or close together with the other three polesType B: The N-pole is not equipped with an overcurrent release, and the N-pole is opened and closed together with the other three poles (the N-pole is closed first and then opened)Type C: N-pole is equipped with an overcurrent release, and the N-pole is opened and closed together with the other three poles (N-pole is closed first and then opened)Type D: N-pole is equipped with an overcurrent release, and the N-pole is always connected and does not open or close together with the other three poles5. The customer did not make a request and supplied according to type B. Detailed Photos  Product ParametersModelHZM66-63HZM66-125HZM66-250HZM66-400HZM66-630HZM66-800Rated current of shell frame level Inm (A)63125250400630800Rated current In (A)10,16,20,2532,40,50,63,16,20,25,32,4050,63,80,100,125100,125,140,160180,200,225,250225,250,315350,400400,500,630630,700,800Rated working voltage Ue (ACV)400400,690,400,400400,690,400,400400,690,400,400400,690,400,400690,400,400Rated insulation voltage Ui500800800800800800Number of poles3343343334333433343343Rated limit short-circuit breaking capacity levelL MLMMHLMMHLMMHLMMHM HRated limit short-circuit breaking capacity level Ics (KA)AC690V 1010151520AC400V25 50356565853565658550858510050858510085100AC230V      Rated limit short-circuit breaking capacity level Ics (KA)AC690V 1010151520AC400V18 352240405052540405035505065355050655065AV230V      Operational performance (times)power supply600060003000200015001000No power supply850085007000400040002500Overall dimensionsL135150165257270280M781039212292107142107150150198150182182240182210280210H73.581.5688686103106.5110115.5Flashover distance(mm) 0,≤500,≤500,≤50≤50≤100≤100THE USE OF CONDITIONS1.
