Circuit Breakers

A circuit breaker is an electrical devices that interrupt current flow in an electrical circuit to protect the circuit from damage. The 8345-F01A-R0M1-DB1B1B-20A is a medium voltage combination motor circuit breaker specifically designed for the protection of combination motor control and distribution circuits. It can be used to control both AC and DC motor circuits, as well as distribution systems.

Application Field

The 8345-F01A-R0M1-DB1B1B-20A is extremely versatile and can be used for a number of applications. In motor circuit applications, it can be used as safety protection against overcurrent, undercurrent, and short-circuits. It can also be used as an disconnect switch for troubleshooting and circuit maintenance. In distribution applications, the 8345-F01A-R0M1-DB1B1B-20A can be used to isolate individual distribution sections or equipment in order to prevent cascading faults.

Working Principle

The 8345-F01A-R0M1-DB1B1B-20A works by sensing the current flowing through the circuit. If the current exceeds certain limits, the circuit breaker will trip and the current flow will be interrupted. The tripping can be caused by either an instantaneous change in current flow or a continuous current overload. The circuit breaker has two operating handles, one to operate the breaker and one to reset the breaker after it has tripped. Both of these handles must be operated in order for the breaker to trip and reset properly.

Conclusion

The 8345-F01A-R0M1-DB1B1B-20A is a versatile medium voltage circuit breaker that can be used for a variety of applications. It works by sensing the current flowing through the circuit and tripping when it reaches certain limits. This provides protection against overcurrent, undercurrent, and short-circuits. It can also be used as an disconnect switch for troubleshooting and circuit maintenance.
