Circuit breakers are designed to protect an electrical circuit from damage caused by excess current. This is accomplished by interrupting the flow of electricity when a fault is detected. They are used in both residential and commercial applications, as well as in industrial applications. The JLE-3-40174-225 circuit breaker is an example of a circuit breaker designed for industrial applications.

JLE-3-40174-225 Application Field

The JLE-3-40174-225 circuit breaker is designed for heavy-duty applications. It is a three-pole, frame-mounted breaker which can be mounted in AC or DC applications. The breaker can be used to protect low-voltage (less than 600VAC/VDC) circuits from overloads and short circuits. The rated current of the breaker is rated up to 225A and it has a 400kAIC interrupting capacity. The breaker is also UL-listed and is designed to meet IEC 60950-1 safety standard.

JLE-3-40174-225 Working Principle

The JLE-3-40174-225 circuit breaker works by detecting an excessive current flowing through a circuit and then automatically disconnecting the circuit to prevent further damage. This is done by means of a thermal-magnetic trip unit. The trip unit contains a bimetal strip which is heated by the excess current. Once the strip reaches a certain temperature the magnetic field of the strip trips the breaker, thereby disconnecting the circuit.

The breaker also has an adjustable trip setting which allows the user to adjust the current which will trip the breaker. This is done by adjusting the current setting on the trip unit. The adjustable trip range of the breaker is from 7.5A to 225A, so the user can adjust the breaker to trip at the current level which is appropriate for the particular circuit. The breaker also has a manual reset button which allows the user to reset the breaker after it has been tripped.

Conclusion

The JLE-3-40174-225 is a three-pole, frame-mounted circuit breaker which is designed for industrial applications. The breaker is rated up to 225A and has a 400kAIC interrupting capacity. The breaker has a thermal-magnetic trip unit which detects an excessive current and trips the breaker to protect the circuit. The breaker also has an adjustable trip setting which allows the user to adjust the current at which the breaker will trip. The user can also reset the breaker manually after it has been tripped. The JLE-3-40174-225 circuit breaker is designed to protect low-voltage circuits from overloads and short circuits.
