L87 Motor Protection

L87 smart motor protector possesses the characteristics of strong anti-jamming ability, stable and reliable operation, digitization, intellectualization and networking. The protection can protect the starting time-out, overload, blocking/blocking, phase-breaking, unbalance, under-load, grounding/leakage, over-voltage, under-voltage, phase sequence, over-power, under-power, temperature, external faults and other situations occurring during the operation of the motor. The SOE fault event recording function, displayed by status indicators on Chinese LCD display, enables the on-site maintenance personnel to identify the cause of the faults. The protection displays the motor's running status clearly and directly. It is applicable for coal mine, petrochemical, smelting, electric power, ship, building etc. The protection has RS485 remote communication interface and DC4~20mA analog output, which facilitates to form a network system with control units such as PLC and PC, to monitor motor operation remotely.
