Hzmm66-100L/3300 Plastic Shell Type Circuit Brealers

The HZMM66 series molded case circuit breakers (hereinafter referred to as circuit breakers) have a rated insulation voltage of
800V(HZMM66-63 500V), suitable for infrequent switching and infrequent motor starting in circuits with AC 50H2 (or 60Hz), rated working voltage of 69oV (HZMM66-63 is 40oV), rated working current up to 800A. The circuit breaker has overload and short circuitThe 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: • - ∞

CLASSIFICATION
The circuit breaker meets the standards: 1EC60947-2, GB14048.2
1.1 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; quadrupole
1.5 According to attachments: alarm contact, auxiliary contact, shunt release, undervoltage release;

Model and its meaning
1. Circuit breakers for power distribution do not have a code: protection motors are represented by 2
2. 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 poles
Type 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 poles
5. The customer did not make a request and supplied according to type B.
