Introduction: CHINT/CHINT contactor NC11 is mainly used in the meter box to control the power supply system of the meter: under normal circumstances, the main contact of the contactor is kept on (that is, the main contact is normally closed at four poles, and one of the poles is used for the protection of the zero line short circuit for the user), only when the user is in arrears, the power supply department can give the contactor a signal to energize the contactor coil, so as to cut off the power supply. In addition, it can also be used in power distribution cabinets in cold storage rooms, laundry rooms, etc. It can be used in circuits with an AC 50Hz or 60Hz rated operating voltage up to 400V and a rated operating current up to 65A under the AC-3 usage category for long-distance switching and breaking circuits. Reliability.
