FIX IT FAST, WITH OUR PARTS!

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

 

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.
