Compact design
Two integral current transformers
Under-load protection (Dry-run protector)
Wide current adjustment range
Definite trip time characteristic
Manual(instantaneous)/electrical(remote)reset ambient insensitive
NON-fail-safe operation
Two of the three phase load currents are detected by integral current transformers,and the internal solid state circuitry compares with preset underload.Over 60A load requires external CTs.When the current level falls off below set point,red LED illuminates and after the preset delay time,internal SPDT relay switches output contacts.Red LED remains illuminated indicating under current trip has occurred.Manual or remote electrical reset by interrupting control supply,is possible,and also optional Auto reset(immediate) available.With visual aid of the LED,the actual load currents can be determined.Simply adjust the load knob clockwise until the red LED flickers.Red LED flashes at the 100% of actual load current.Test button is provided for testing normal operation and interrity of the unit with or without motor running.Standard internal output mode is relay de-energized in normal condition.Avaiable with fixed supply voltage(110,220/240VAC,50/60HZ,or 24/48VAC/DC)
Ideal for protecting from the open heater and pumps from dry run.
