PMAC800 motor protector is an intelligent digital motor protection device used in LV fields.

PMAC800 motor protector integrates relay protection, measurement and
control functions, with network communication technology and distribution intelligent
technology in MCC control center.PMAC800 motor protection controller is a microprocessor-based unit. It consists of two parts: main unit and display unit. Main unit can run independently to implement various protections, measurement and control functions. Extended unit meansdisplay unit or display unit + 8 extended DI. It is auxiliary and can't run independently.

Through extended unit, users can get measurement value, DI/DO status,alarm and trip information, control motors and set various parameters. Features:PMAC800 motor protection controller provides protection functions such as start overtime protection, overload protection, over-current protection, phase failure protection, current unbalance protection, earth fault/leakage current protection, short circuit protection, under-load protection, temperature (PTC/NTC) protection, over-voltage protection, under-voltage protection, under power factor protection, phase sequence error protection and EEXE overload protection. Provides protection mode, direct starter, reversing direct starter, star/delta starter and autotransformer starter motor starting control typesProvides measurements of three-phase current, three-phase voltage, zero phase sequence current, active power, reactive power, power factor, frequency and active energy measurementProvides 8 DI for status, start, stop and reset signals Provides 4 DO to meet varies of starting control types and protection action8 trip events can be stored in non-volatile memoryProvides 4~20mA analog output for DCS
