CHINT 200 amp circuit breaker

CHINT (Zhejiang Chint Electrics Co., Ltd.) is a well - known electrical equipment manufacturer, and its 200 amp circuit breakers offer a variety of features and are suitable for different applications. Here is a detailed introduction:

1. Product Types

- **Molded Case Circuit Breakers (MCCB)**

    - CHINT's MCCBs with a 200 - amp rating are commonly used in industrial and commercial power distribution systems. They provide reliable protection against overloads, short - circuits, and sometimes ground faults. For example, the CDM1 series MCCBs can be configured with different tripping characteristics to meet various application requirements.

 - **Air Circuit Breakers (ACB)**

    - ACBs are often used in high - power applications. CHINT's 200 - amp ACBs, such as some models in the DW series, are designed to handle large - scale electrical loads, providing high - level protection and stability. They usually have more advanced protection functions and can be used in important power distribution centers.

2. Key Features

- **Overload Protection**

    - These circuit breakers can detect prolonged over - current situations. When the current exceeds the rated 200 amps for a certain period, the breaker will trip to prevent damage to the electrical equipment and wiring. For example, in an industrial workshop where multiple machines are running, if the total current exceeds the rated value due to abnormal operation of a machine, the circuit breaker will act.

 - **Short - Circuit Protection**

    - In the event of a short - circuit, where the current suddenly rises to a very high level, the 200 - amp CHINT circuit breaker can quickly trip. This is crucial for preventing electrical fires and damage to expensive electrical components. The short - circuit tripping time is usually very short, often within milliseconds.

 - **Adjustable Tripping Characteristics**

    - Some of CHINT's 200 - amp circuit breakers allow users to adjust the tripping settings. This flexibility enables them to be customized according to the specific requirements of different electrical systems. For example, in a system with high - inrush current loads (such as motors), the user can adjust the overload and short - circuit tripping thresholds.

 - **High Breaking Capacity**

    - They are designed to have a high breaking capacity, which means they can safely interrupt a large short - circuit current without being damaged. This is important in ensuring the safety and reliability of the electrical system, especially in high - power applications.

3. Application Scenarios

- **Industrial Applications**

    - In factories, a 200 - amp CHINT circuit breaker can be used to protect large - scale production equipment, such as conveyor belts, industrial furnaces, and large motors. It ensures that the equipment operates safely and that the production process is not interrupted by electrical faults.

 - **Commercial Buildings**

    - In shopping malls, office buildings, and hotels, these circuit breakers are used in the power distribution systems to protect lighting, air - conditioning, and other electrical equipment. They help to maintain a stable power supply and prevent electrical accidents.

 - **Residential Complexes (for large - scale power distribution)**

    - In some large - scale residential complexes, 200 - amp circuit breakers may be used in the main power distribution cabinets to ensure the safety of the overall power supply to multiple households.

4. Installation and Maintenance

- **Installation**

    - The installation of CHINT 200 - amp circuit breakers should follow the manufacturer's instructions and relevant electrical installation standards. It is important to ensure proper wiring, correct connection of the incoming and outgoing cables, and secure mounting in the distribution panel.

 - **Maintenance**

    - Regular maintenance is required to ensure the normal operation of the circuit breaker. This includes checking the contacts for signs of wear or overheating, inspecting the mechanical parts for smooth operation, and verifying the accuracy of the protection settings. If any problems are found, the relevant parts should be repaired or replaced in a timely manner.
