Detailed Product Description

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
