- **Overload and Short-circuit Protection**: The CHINT moulded case circuit breaker has three-stage protection characteristics of long-time delay for overload, short-time delay for short circuit, and instantaneous action for extremely large short circuits. It can accurately detect overload and short-circuit faults in the circuit and quickly cut off the circuit to protect the safety of electrical equipment and lines.

- **Multiple Types of Trip Units**: There are various types of trip units available, such as electromagnetic type, thermal-magnetic type, and thermally adjustable magnetic fixed type, etc., to meet different load characteristics and protection requirements.

- **Good Insulation Performance**: By adopting high-strength environmentally friendly plastic double-layer cover composite technology, etc., it has good insulation performance and sealing performance, which can effectively prevent electric shock and electrical short-circuit accidents.

- **Flexible Wiring Methods**: Some models of CHINT moulded case circuit breakers support free incoming wiring from both the upper and lower sides. The wiring methods are relatively flexible, making installation and cabling convenient.

- **Rich Accessories**: It is equipped with a variety of accessories, such as electric operating padlocks, handle locks, LMI mechanical interlocks, etc., which can achieve more functions and safety protection.

### Application Scenarios

- **Industrial Sites**: It is used in industrial electrical systems such as factories and workshops to provide overload and short-circuit protection for equipment such as motors, distribution boxes, and production lines, ensuring the safe and reliable operation of industrial production. For example, in an automated production line, it supplies power and provides protection for each motor and equipment.

- **Commercial Buildings**: It is suitable for the low-voltage power distribution systems of commercial places such as shopping malls, hotels, and office buildings, providing protection and control for electrical equipment such as lighting, air conditioners, and elevators. For instance, in the power distribution room of a shopping mall, it is used to distribute electrical energy and protect the electrical equipment on each floor.

- **Residential Buildings**: It can be installed in the distribution boxes of residential houses to protect household electrical appliances such as air conditioners, refrigerators, and washing machines, preventing safety accidents such as electrical fires caused by overload or short circuits.

- **Other Fields**: It also plays an important role in places with high requirements for electrical safety, such as hospitals, schools, and data centers, providing reliable protection and stable power distribution for the electrical systems of these places. For example, in the row cabinets of a data center, the CHINT MCCB distribution box is used to supply power and provide protection for servers and other equipment.

What is the price range of the CHINT MCCB distribution box?

The price of the CHINT MCCB distribution box varies depending on specific models, specifications, functions, and purchasing channels, etc. The following are the price situations of some common products:

- **Small Household Distribution Boxes**: For example, the CHINT PZ30-10 distribution box is sold at about 88 yuan. This kind of distribution box is usually used in households or small places, and is equipped with relatively basic moulded case circuit breakers inside, which can meet the protection and distribution needs of general household electricity.

- **Industrial or Commercial Distribution Boxes**:

    - The price of a single CHINT plastic case type 3P circuit breaker NM1-63S/3300 - 50A is about 198 yuan. When used in a distribution box, the price of the whole distribution box will be higher when adding the box body and other accessories. If it is a distribution box containing multiple NM1-63S/3300 circuit breakers, the price will vary according to the number of circuit breakers configured and other functional modules, generally ranging from several hundred yuan to several thousand yuan.

    - The price of a single CHINT plastic case type 3P circuit breaker NM1-250S/3300 - 160A is about 277 yuan. Distribution boxes containing such relatively large-sized circuit breakers are usually used in industrial or large commercial places, and their prices will vary greatly depending on specific configurations and functional requirements, possibly being around several thousand yuan.

If it is a customized CHINT MCCB distribution box, the price will also be affected by customization requirements, such as special dimensions, protection levels, intelligent monitoring functions, etc., and the price may be higher. When purchasing, it is recommended to consult the official distributors of CHINT, such as Hebei China Electric, or professional electrical equipment suppliers to obtain accurate quotations.
