Circuit Breakers: JLE-1-31278-1 Application Field and Working Principle

Circuit breakers are an important components of electrical systems, providing over-current protection and other safety and maintenance benefits. The JLE-1-31278-1 is designed to provide a combination thermal/magnetic circuit protector for automotive and other electrical systems. In this article, we will explore the application fields and working principles of the JLE-1-31278-1 circuit breaker.

Application Fields

The JLE-1-31278-1 is an ideal circuit protector not just for automotive systems, but also for a variety of industrial electrical devices. In automotive applications, the device can be used for the protection of main power, starter, and other electric circuits. It can also be used in different industrial control applications, and is useful where temperature changes must be monitored, such as for temperature control in motor operated equipment. Industrial machinery such as elevators, grinding machines, electric fans, compressors, air-conditioning systems, and lighting also benefit from the thermal/magnetic protection of the JLE-1-31278-1. The device can also be used for general-purpose circuit protection in home appliances, lighting fixtures, and other high-end electrical applications.

Working Principle

The JLE-1-31278-1 utilizes a combination thermal/magnetic circuit protection achieve precise over-current protection. When an overload or short-circuit condition is detected, the device quickly disconnects the circuit, isolating the circuit from the power source and avoiding damage to sensitive components.When over-current protection is activated, the device performs two functions suited to the overload or short-circuit condition. First, a strong electromagnetic field is produced by the JLE-1-31278-1. This magnetic field triggers an electromechanical contact, directing the current flow away from the faulted circuit. The second component of the thermal/magnetic protection process is the heating element. This element consisting of a small wire embedded in material that will heat up with current. As current flows through the device, the heating element slowly increases in temperature. When a certain temperature threshold is reached, the thermal contact in the device opens and physically disconnects the circuit. This double-action protection process ensures the circuit will remain protected from over-current and temperature fluctuations.

Conclusion

The JLE-1-31278-1 circuit breaker is a sturdy and reliable solution to a wide variety of electronic protection needs. Its combination thermal/magnetic protection capabilities make it an ideal choice for automotive and other industrial applications, wherever precise over-current protection is needed. With the JLE-1-31278-1, electricians and engineers have an effective and versatile solution to keeping sensitive electrical systems safe.
