Description

Features
Mode of Operation:
If all 3 phases are relatively equal and in proper sequence, the normally open contacts (Y/Y-OUT) will close when 24 volts is applied between C and Y 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 ICM401 is energized, the contacts will open immediately and will remain open until the error is corrected.
An illuminated green LED indicates the output is energized, and an illuminated red LED indicates there is a fault and the output is de-energized.
- 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 ICM403

Great Product for the Price!
Our company has been using this product for years and have had great success with it. We do marine refrigeration and air conditioning and the majority of the equipment is 3 phase. It is a great value for the price!

Functions as needed
This part was holding an HVAC unit out of service. Normally it detects phase loss, and without it could damage your system. New one worked great as needed, plug and play and the system was up and running again.
