Two of three phase motor currents are monitored by current transformers. The internal solid state circuitry compares with preset current level.
When load currents exceeds the preset trip level,red LED iIIuminates,after the preset time, the device trips, and changes internal SPDT relay
contacts.Red LED remains illuminated indicating an overload trip has occurred. Until manual or remote electrical reset by interrupting supply,
is initiated.If load current falls off below setpoint before preset delay, device resets trip timer. With the aid of LED flashing at 100% of
preset load, actual load currents can be determined without the aid of Ammeter. Test button provides the means of testing service-worthiness
and integrity of the device. Internal relay iS energized in normal operation condition(fail—safe) and will not become ready mode with either
supply lost or own failure.
*Starting delay range : O.2—30 seconds.
*Trip delay time range:0.2-10 seconds.
*May be used as electronic shearpin by setting trip time to minimum.
