Circuit Breakers

The R21-1REF..00174874 circuit breaker is a device designed to protect electrical circuits from overloading or short-circuiting. It works by preventing too much current from passing through a circuit. When the current levels rise to a level that is unsafe for the system, the circuit breaker trips and shuts off the flow of electricity. This helps prevents damage to the circuits and protects people from electric shock.

Application Field

Circuit breakers are typically used in residential, commercial, and industrial settings to protect electrical circuits from damage. This includes protecting circuits from fluctuations in voltage, overloading, and short-circuits. They are also used in power plants, substations, and transformers to protect the power transmission system from excessive current or voltage levels. Circuit breakers are also used in marine and motor vehicles to protect sensitive electronic equipment from shorts and other electrical problems.

Working Principle

The R21-1REF..00174874 circuit breaker is a thermal-magnetic model. This means that two separate trips are combined in one device. The thermal element works by measuring the rise in temperature of the circuit due to increased current flow. When the temperature rises too high, the thermal element trips and disrupts the flow of electricity. The magnetic component works by measuring the current in the circuit. When the current level exceeds the rating of the circuit breaker, the magnetic element trips and shuts off the flow of electricity.

The R21-1REF..00174874 circuit breaker also has a trip flag feature. Once the breaker has tripped, the trip flag will be in the off position, indicating that the breaker has tripped. This can be reset by pressing the reset button, which will bring the trip flag back to the ready position. The trip flag feature helps to ensure that the breaker has been reset before it is put back into operation.

The R21-1REF..00174874 circuit breaker is designed to be used in residential, commercial and industrial settings to protect circuits from overloads and other electrical problems. The combination of the thermal and magnetic elements make the breaker highly reliable and provide superior protection against electrical issues that could potentially damage electrical components and the people using them.
