Product Description

Hydraulic magnetic molded case circuit breakers have become an indispensable and important part of modern power systems due to their efficient protection functions and wide applicability. When selecting and installing, they should be reasonably configured according to specific circuit requirements and load types to ensure the safe and stable operation of the system.The following are some of the main places and application fields where hydraulic magnetic molded case circuit breakers are suitable:

1.Industrial Equipment:

Hydraulic magnetic molded case circuit breakers are commonly used for power protection of various industrial equipment, such as motors, transformers, generators, etc. These devices may be overloaded or short-circuited during operation, and the use of circuit breakers can effectively prevent equipment damage.

2.Power distribution system:

Hydraulic magnetic molded case circuit breakers are widely used in power distribution and protection in distribution cabinets and distribution systems. They can ensure that the power supply is quickly cut off when the current is abnormal, protecting the safety of downstream equipment and lines.

3.Building Electrical System:

In the electrical systems of commercial and residential buildings, hydraulic magnetic molded case circuit breakers are used to protect circuits from fire and other safety hazards caused by overloads or short circuits. They are usually installed in distribution boxes to ensure safe and reliable power supply throughout the building.

4.Transportation:

In railways, subways and other transportation systems, hydraulic magnetic molded case circuit breakers are used to protect power supply systems and ensure the safe operation of trains and related equipment.

5.Renewable Energy Systems:

In solar power generation and wind power generation systems, hydraulic magnetic molded case circuit breakers are used to protect inverters and other power equipment, ensuring that power can be cut off in time when current fluctuates to protect the stability of the system.

6.Data Center and Communication Equipment:

In data centers and communication equipment, hydraulic magnetic molded case circuit breakers are used to protect power systems, ensuring that critical equipment can be protected in a timely manner in the event of power failure, avoiding data loss and equipment damage.
