Product Features
■ Support power parameter measurement (U, I, P, Q, S, PF, F, EP, EQ), voltage and current imbalance degree, voltage and current positive sequence, negative sequence, zero sequence component, three-phase voltage phase Angle, residual current.
■ Protection functions include overload inverse time, overload definite time, grounding, starting timeout, leakage, underload, locked-rotor, obstruction, short circuit, phase, overflow, imbalance (current, voltage, power, less power, over voltage, under voltage, phase sequence, temperature, external fault, tE time, running time alarm, fault alarm.
■ 8 channels programmable DI input, the default use of DC24V power supply, or external active wet contact can be selected (see the selection table).
■ 5 programmable DO output, to meet the direct starting, star - triangle starting, auto-transformer starting, and other starting modes, can be through the communication bus to achieve the master station to the motor remote control "start/stop".
■ Optional anti-shaking function: support immediate restart of shaking power and restart of voltage loss.
■ MODBUS_RTU and PROFIBUS DPV1 communication modules are available for selection.2 MODBUS_RTU communication channels or MODBUS_RTU+PROFIBUS DPV1 communication modules can be chosen.
■ Optional 1 channels DC4-20MA analog output interface, connected with DCS system, can realize the monitoring of field equipment.
■ With fault record, start record, stop record, DI displacement record, restart record and other records of various events, you can view a number of motor operation and maintenance information.
■ The display interface supports Chinese/English LIQUID crystal display

Remarks:
(1)The motor with rated current of 0.4-1.6A can choose the 1A specification motor protector,and the transformer is wound 1 times.The motor with rated current of 1.6-6.3A can choose the 5A specification motor protector,and the transformer is wound 1 time.
(2)Integrated current transformer is used for integrated protector with current specification of 100A and below；The split current transformer is used for the current specification of 100A and below;
250A and 800A current specifications use another type of split current transformer. For the external dimensions of the transformer, please refer to the "external dimensions and installation".
(3)The temperature measurement support sensor type is PTC or NTC or PT100.
(4)After the leakage function (L) is selected, each protector is equipped with a leakage transformer. The dimensions of the leakage transformer are shown in the section "overall dimensions and installation". Leakage transformer is equipped with 2m ± 10cm secondary line as standard. If you need other length, please contact the manufacturer.
