  • The Basics of Molded Case Circuit Breakers EC&M

     · May 01, 1996. The traditional molded-case circuit breaker uses electromechanical (thermal magnetic) trip units that may be fixed or interchangeable. An MCCB provides protection by combining a temperature sensitive device with a current sensitive electromagnetic device. Both these devices act mechanically on the trip mechanism.

  • Electrical Isolator or Electrical Isolation Switch

     · Definition of Isolator. Circuit breaker always trip the circuit but open contacts of breaker cannot be visible physically from outside of the breaker, and that is why it is recommended not to touch any electrical circuit just by switching off the circuit breaker. So for better safety, there must be some arrangement so that one can see the open condition of the section of the circuit before

  • How does fuse protect circuit?Science ABC
