ESX10-124-DC24V-0,5 Circuit Breakers: Application Field and Working Principle

Circuit Breakers are a fundamental safety element of modern electrical distribution and apparatus, used in virtually every branch of industry. The ESX10-124-DC24V-0,5 is a specific type of Circuit Breaker that is closely associated to the general category due to its protective circuit breaker design. This article will discuss the application field, as well as its operating principle, of the ESX10-124-DC24V-0,5 Circuit Breaker.

Application Field

The ESX10-124-DC24V-0,5 Circuit Breaker is primarily used for protection against short circuits and overloads in low-power DC circuits, such as those found in communications, industrial control, and automation systems. Its protective qualities extend to both overvoltage and undervoltage circumstances. The ESX10-124-DC24V-0,5 is especially designed for continuous current circuits of up to 50V, as well as intermittent services up to 55V and peak current 100A. Due to its protection limits, it will not trip during starting of inductive motors. As it has a miniature arc length, it can easily fit in small spaces, such as those found in the control cabinets of mobile machines, medical or automotive equipment.

Working Principle

The operating principle of the ESX10-124-DC24V-0,5 Circuit Breaker is based on the same principles that apply to other Circuit Breakers. Its design includes a magnetic tripping system to interrupt the current in the event of a fault or overload. A reed switch acts as an isolated switch to open the contacts in a very short time when a current exceeding the adjustable trip range flows. The contacts then remain open until the reset button is pressed, thus deactivating the tripping mechanism.When a short circuit occurs, the magnetic field generated in the solenoid coil creates a radial force on the plunger, which, as it approaches its operating point, increases the tripping speed. As the current starts to flow, the plunger is attracted to the coil, and once it reaches its trip point, it immediately opens the contacts. When an overload occurs, the strain on the contacts inside the Circuit Breaker generates a certain amount of heat. The thermal system of the ESX10-124-DC24V-0,5 contains a heat-sensitive bimetallic element that opens the contacts when they reach their preset temperature. Thus, the tripping mechanism can be reactivated in either case.

Conclusion

The ESX10-124-DC24V-0,5 Circuit Breaker is particularly designed for low-power DC circuits in communications, industrial control, and automation systems. It is especially suitable for dealing with short circuits and overloads, as well as overvoltage and undervoltage situations. Its operating principle is based upon the same principles that apply to other Circuit Breakers. The magnetic tripping system can interrupt the current due to a fault or overload, while the thermal system will open the contacts when they reach their preset temperature.
