​ZBQ3 series intelligent dual power automatic conversion switch

ZBQ3 series intelligent dual power automatic conversion switch is composed of two triple or quadrupole plastic shell circuit breakers and their accessories (auxiliary, alarm contacts), mechanical interlocking transmission mechanism, intelligent controller, etc.It is divided into integral type and split type: two structures.The integral type is the controller and the actuator mounted on the same base; the split type is the controller mounted on the cabinet panel, the actuator mounted on the cabinet by the user, the controller is connected to the actuator with a cable of about 2m long.Its characteristics are: The reliable mechanical interlocking device and electrical interlock protection between the two circuit breakers completely eliminates the possibility of two closing at the same time. Intelligent controller uses single-chip machine as the control core, simple hardware, powerful function, convenient expansion, high reliability.With short circuit, overload protection function, over pressure, underpressure, missing phase automatic switching function and intelligent alarm function. The automatic switching parameters can be freely set externally. With the intelligent protection function of the operating motor. The device has a fire control circuit. When the fire control center gives a control signal to the intelligent controller, both circuit breakers enter the switch state.Leav
