ICM402 Phase Loss and Removal Protection, 190-600 VAC

Features Low cost 3 phase protection for single side Monitors for phase reversal, phase loss, unbalance % as a function of input voltage Bright LED indicators for ON and FAULT Universal 3 phase input: 190-600 VAC Highly reliable passive electronics Easy to install, no adjustments Less than 1 second phase loss response Automatic reset from a fault condition Compact packaging: fits almost anywhere Epoxy coated for added protection Works great with the ICM450 for load side monitoring of part winding start motors and multiple compressor systems For open board model, order ICM404 Mode of Operation:If all 3 phases are relatively equal and in proper sequence, the normally open contacts (Y/Y-OUT) will close when 115/230 volts is applied between C and 115/230 VAC terminals. If the phases are out of sequence, or if one is missing, the contacts will never close. If a phase is lost while the ICM402 is energized, the contacts will open immediately and will remain open until the error is corrected. An illuminated green LED indicates that the output is energized, and an illuminated red LED indicates that there is a fault and the output is de-energized.
