Circuit Breakers

Application Field and Working Principle

A circuit breaker is a device designed to protect electrical circuits from damage that could result due to excessive current, short circuits, and ground faults. Circuit breakers are commonly used in a host of variable applications including industrial, commercial, and domestic circuits. The PR21-62-3.00A-38842-1-V is an example of an industrial circuit breaker.

Circuit breakers are typically composed of two main components: a switch and an overload protector. The switch component is responsible for interfering with the flow of electricity, while the overload protector component is responsible for tripping the circuit when current levels exceed safe levels. Together, these two components form an effective mechanism for protecting the electrical system.

The PR21-62-3.00A-38842-1-V industrial circuit breaker is specifically designed to monitor the current flow in commercial, industrial and residential circuits and automatically shut down the system when current levels exceed predetermined levels. This is achieved through the use of a thermal-magnetic switch. The thermal-magnetic switch consists of two separate mechanisms that are set at different thresholds. When current levels exceed a predefined level, the magnetic switch is activated and opens the breaker, thereby deactivating the system.

With the PR21-62-3.00A-38842-1-V industrial circuit breaker, the thermal-magnetic switch can be adjusted to accommodate different current levels. The current levels at which the switch is activated can be determined depending on the application. By adjusting the thermal-magnetic switch, the user can prevent unnecessary tripping of the circuit breaker.

The PR21-62-3.00A-38842-1-V can be used for a variety of applications including industrial, commercial and residential circuits. The adjustable thermal-magnetic switch makes it ideal for protecting circuits from overloading due to excessive current levels. With its reliable design and robust construction, the PR21-62-3.00A-38842-1-V industrial circuit breaker is a reliable and cost-effective solution for any application.
