Circuit Breakers

A 1B8UR is a type of circuit breaker that is used in a variety of applications. Circuit breakers are important components in both residential and commercial electrical systems. This type of breaker is designed to open or close the electrical circuit when it senses an overload, or when it needs to be reset after a power failure.

Application Field of 1B8UR

The 1B8UR is used for a wide range of applications such as residential, commercial and industrial situations. Some of the common applications include motor starting, signage, electronic equipment, lighting, air conditioning and refrigeration systems, pumps and agricultural equipment. The 1B8UR circuit breaker is also used in factories, where they are required to cut out electric faults.

This type of circuit breaker is often used in surge and overvoltage protection devices. The 1B8UR breaker is designed to be used with a manual reset switch or automatic reset and can be adjusted to different current and voltage values. Some 1B8UR breakers are designed with a small indicator window that shows the current voltage.

Working Principle of 1B8UR

The 1B8UR circuit breaker is a mechanical device that has an internal system of operation that makes it able to cut off the electric current in the event of an overload or fault. The 1B8UR breaker has an internal system composed of an electromagnetic control arm, a central spring and an actuator. The control arm is connected to the spring, and the actuator is connected to the control arm. When an overload occurs, the voltage increases and the electromagnetic force created by the control arm lifts the actuator arm and opens the circuit. When the overload is removed, the spring pushes the actuator arm down and closes the circuit.

In addition to the tripping system, the 1B8UR breaker has a thermal protection system. The thermal protection system works by increasing the resistance of the internal bimetallic strip when the temperature of the strip rises. This causes the current draw to decrease and eventually the current will reach a point where the breaker will trip and open the circuit.

The 1B8UR circuit breaker is designed to be both reliable and easy to reset. After a power failure, the manual reset switch needs to be pushed in order to reset the breaker and return it to its normal state. The 1B8UR circuit breaker is a simple and efficient device that is used to protect electrical systems from power surges and overloads.
