TBB Contactor-Switched Low-Voltage Reactive Power Compensation Unit

Features:
Compensation device are make up of power capacitors, power factor meters(reactive power compensation breakers controller), the total power controller (circuit breaker), switching capacitor contactors, miniature circuit mainly and so on.There are power factor meter, ammeter, voltmeter, lights and other devices on the compensation panel, user-friendly real-time observation.Compensation device cabinet is made of high quality cold-rolled steel, good flat and strong corrosion resistance for the spray outer surface.Full protection function, such as over voltage, over current, short circuit and so on, the parameter setting expediently, automatically exits the relevant operation when an external fault occurs and automatically resume operation after power.
Suitable for：
Transmission and distribution, power transmission stations and improve the power factor, etc.
