Introduction of 280856 Circuit Breakers

Circuit breakers are automated switches located within electrical system, designed to prevent the system from additional damage due to current overload or short circuit. Circuit breaker is a vital component to ensure the safety and reliability of power system. Models of 280856 Circuit Breaker are widely used in various areas, like industrial, commercial, residential and so on.

Application Field of 280856 Circuit Breakers

The 280856 circuit breaker is designed to meet the requirements of applications such as low voltage switchgear and panel boards, industrial control, motor control and distribution. Its main application fields are summarized as following.

1.Panel circuit breaker

The 280856 circuit breaker can be used as a distribution panelboard to protect and switch the distribution power system. It is used to control main power path and branch circuit, providing protection to equipment and people. This circuit breaker should be installed in the same area with power device.

2.Industrial control

The 280856 circuit breaker is used in industrial control projects to provide reliable circuit protection for motors and other equipment. This circuit breaker is usually used to control and protect the power sources and actuating elements, such as solenoid valves, motor starters and contactors in process automation systems.

3.Motor control

This type of circuit breaker can also be used in motor control applications. It is designed to control motor loads and protect them from overload and short circuit efficiently. This type of circuit breaker also avoids direct contact between workers and the equipment, which increases safety.

4.Power distribution

The 280856 circuit breaker is used to control and protect the supply circuits of distribution systems. This circuit breaker performs its job by disconnecting the current once it detects an excess of current in the system. By isolating the circuits, it avoids the risk of a short circuit and other dangerous incidents.

Principle Working of 280856 Circuit Breakers

The 280856 circuit breaker has two main functions: thermal protection and magnetic protection. Thermal protection works automatically by disconnecting the power from the circuit when the overload current is detected by a thermal element. On the other hand, the magnetic protection works faster and disconnects the power when an extreme current is detected by an electromagnetic element.When an overload or short circuit occurs, the thermal device or the electromagnetic device will be activated, allow high current arc which passes through the contact and move to the arc chamber. In the arc chamber, there is an arc extinguishing medium and insulators, so that the arc can get extinguished quickly and the contact separation can be achieved in a very short time.After the disconnection of the contacts, the breaker is reset by either a manual or an automatic reset operation. During the automatic reset operation, the contacts will be reset when the voltage in the circuit decreases to a normal level. In the manual reset, the required reset must be done manually by the user. This circuit breaker can also be used for controlling, as it can be operated manually.

Conclusion

280856 Circuit Breakers have a wide range of applications, from panel circuit protection to industrial control, motor control, and power distribution. It can offer the system reliable circuit protection by using two main functions: thermal protection and magnetic protection. This type of circuit breaker can also be used for controlling manually or automatically. With their high performance and simple maintenance procedures, they are one of the most common choices of circuit breaker.
