Delixi CDW3-3200H CDW3 series ACB Air Circuit Breaker

Here is the technical parameter introduction of the DW3-3200H ACB Air Circuit Breaker:

Rated Voltage

The rated voltage of the DW3-3200H is typically 400V, 690V, etc., which is suitable for different power distribution systems. It can ensure normal operation and reliable insulation within the rated voltage range.

Rated Current

The rated current of this circuit breaker is 3200A. It means that under normal operating conditions, the breaker can continuously carry a current of 3200A without overheating and other problems, which is suitable for high - power electrical equipment and large - current circuits.

Breaking Capacity

The DW3-3200H has a high - breaking capacity. For example, in the 400V voltage level, its breaking capacity may reach 80kA or more. This parameter indicates the maximum short - circuit current that the breaker can safely interrupt. When a short - circuit fault occurs, the breaker can quickly cut off the circuit to protect the safety of the power system and equipment.

Rated Frequency

Usually, the rated frequency is 50Hz or 60Hz, which is consistent with the power frequency of most power grids. This ensures that the circuit breaker can work stably in the corresponding power grid environment.

Trip Characteristics

Overcurrent Trip: The breaker is equipped with an overcurrent protection function. When the current exceeds the set overcurrent value, the breaker will trip within a certain time. The overcurrent setting value can be adjusted according to the actual load requirements to ensure the protection of the circuit from overload.

Short - Circuit Trip: In the case of a short - circuit fault, the breaker can quickly detect the short - circuit current and trip within a very short time, usually within milliseconds. This rapid response helps to minimize the damage caused by short - circuit faults.

Mechanical Life

The mechanical life of the DW3-3200H is generally designed to be more than 10,000 times. This means that the breaker can complete a certain number of on - off operations during its service life without significant mechanical wear and failure, ensuring its long - term reliable operation.

Electrical Life

Under rated operating conditions, the electrical life of the circuit breaker can reach several thousand times. This reflects the ability of the breaker's contacts and other electrical components to withstand the electrical erosion and wear during normal operation, ensuring the stability and reliability of the electrical connection and disconnection.

Degree of Protection

The CDW3-3200H usually has a certain degree of protection, such as IP30 or higher. This means that the breaker has a certain ability to prevent solid foreign objects and water from entering, which can protect the internal components from damage and ensure its normal operation in different environments.
