About mccb circuit
MCCB
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. Depending upon the application and required protection, an MCCB will use one or a combination of different trip elements that protect against the following conditions: Thermal overloads; Short circuits; and Ground faults.
