MFC922 series intelligent low voltage motor protector
1.1 Product Brief
MFC922 series intelligent low-voltage motor protector is a smart protector issued by our company for the failure of low-voltage motors in various applications. It is a high cost-effective, stable and reliable according to IEC international standards. It integrates relay protection, The intelligent motor protector with measurement, control and communication as a whole can cooperate with various sensors for protection and judgment, and truly realize the intelligent detection control and protection functions.
The protector is used to operate the contactor in the AC motor control circuit of AC 50Hz, rated insulation voltage to 660V-rated current to 800A, in the event of overheating, overload, locked rotor, phase unbalance, grounding or leakage, undervoltage, overvoltage It is used to protect the motor breaking circuit breaker when the fault occurs.
The protector is based on microprocessor and fieldbus technology, adopts a modular design, the product is small in size, compact in structure, and easy to install. It can be directly installed in the low-voltage distribution terminal MCC cabinet and various drawer cabinets with more than 1/4 module Use, compared with the traditional motor protection control scheme, reliability and comprehensive cost performance have been greatly improved. It can be widely used in power plants, iron and steel, petrochemical, cement, gas and paper industries, providing safe, reliable and efficient control and protection for electric motors.
1.2 Product Composition
The MFC922 series adopts a modular product structure, including the main body (protection control function module), current transformer module, display module (including a dedicated connection line), and optional MFC922 function modules or accessories as required.
