If DC24V loses, the trip state of 72B will be carried out.
Note2)Even if a 72B UVT coil carries out reset operation of the breaker from a trip state
in the state of no magnetizing, it cannot turn OFF.
Note3)When the magnetization voltage of a coil returns to 24V, it is possible to reset a breaker in the OFF state.
Note4)DC24V-16mA is impressed to 72B auxiliary contact through a terminal box from IOAU-09 PWB.
