Product Detail:

General

ARD3M intelligent motor protector (hereinafter referred to as the protector) is suitable for low-voltage motor circuits with rated voltage up to 660V and integrates protection, measurement, control, communication, operation and maintenance. Its perfect protection function ensures the safe operation of the motor, with logic programmable function, can meet a variety of control methods. Different communication modules can be selected to meet the needs of field communication.

Function:

Protection Type (Default Active Period):

Whole Course:

Overvoltage, undervoltage, voltage imbalance, phase sequence, external fault, overflow protection, starting times, fault times, running time, PTC/NTC temperature protection, insulation monitoring.

When Starting:

Reverse time overload, blocking, phase break, leakage, grounding, starting timeout, short circuit, overflow protection, Overvoltage, undervoltage, voltage imbalance, phase sequence, external fault, number of starts, number of faults, running time, PTC/NTC temperature protection, fixed time overload, insulation monitoring.

In Operation:

Reverse time-limit overload, blocking, phase break, current imbalance, leakage, grounding, constant time-limit overload, under load, short circuit, overflow protection, overvoltage, undervoltage, voltage unbalance, phase sequence, underpower, overpower, external fault, PTC/NTC temperature protection, number of starts, number of faults, running time, insulation monitoring.

When install the meter, loosen the locking screw of the fixing bracket, remove the fixing bracket, insert the instrument into the mounting hole, install the fixing bracket and tighten the screw to make the instrument be firmly installed without loosening. Shape for clamp reed squeeze installation.
