A diagram of a hose bibb vacuum breaker is illustrated below along with a typical installation: Standardized Information for Hose Bibb Vacuum Breaker No information available at this time.
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.o stop this current flow quickly so that major damage can be prevented, the short circuit or instantaneous element of an MCCB is used. A typical time current curve for an instantaneous element, as shown in Fig. 2, shows that it will not initiate a trip until the fault current reaches or exceeds Point 1.
