Function and Use
The NC11 contactor is mainly used in electricity meter boxes to control the power supply system of the meter: Under normal conditions, the main contacts of the contactor are kept closed (i.e., the main contacts are four-pole normally closed, one of which is used for the user's protective neutral shorting). Only when the user has an arrears, the power supply department can send a signal to the contactor to energize the coil, thereby cutting off the power supply. It can also be used in distribution cabinets of cold storage rooms, laundries, etc.
