ICM450A and ICM450A+

Programmable 3-Phase Line Voltage Monitors

For more than two decades, ICM has been an innovator and a recognized leader in the manufacturer of line voltage controls designed to protect your most valuable equipment. The ICM450A and ICM450A PLUS+ are the latest 3-phase offerings, providing superior motor protection from premature failure and damage caused by common voltage faults such as phase unbalance, over/under voltage, phase loss, and phase reversal. 

A design upgrade from our flagship ICM450, these newest models feature an easy-to-read, backlit display that makes quick work of adjusting the variable settings to better tailor the unit to the application. Common ¼” spade terminations eliminate the potential for exposed wires and allow for a better and safer connection. Both models also include menu options for English and Spanish readouts. 

Additionally, the ICM450A PLUS+ offers a real-time clock for the date and time stamp of fault events when they occur along with a Modbus RS485 communications port for communicating with a standard building management system. 

Both the ICM450A and ICM450A PLUS+ are proudly manufactured in the USA by ICM Controls.
