{"product_id":"icm-controls-icm450a-3-phase-line-voltage-monitor","title":"ICM Controls ICM450A Programmable 3-Phase Line Voltage Monitor, 190–600 VAC, Backlit LCD","description":"\u003cp dir=\"ltr\"\u003eThe ICM Controls ICM450A is a programmable 3-phase line voltage monitor built to protect compressors, motors, and other 3-phase loads from premature failure caused by bad incoming power. It continuously watches all three legs and opens its output relay when it detects phase unbalance, high or low voltage, phase loss, or phase reversal. This shuts down the equipment before the fault damages it.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe ICM450A is a design upgrade over ICM's original ICM450. Its backlit LCD shows all three phase voltages at the same time using true RMS measurement, so a technician can read line conditions at a glance without a meter. Every setting can be adjusted from the front panel, including voltage thresholds, unbalance limits, and the delay-on-break timer. That lets you tailor the protection to the equipment and the site's utility conditions. The fault memory stores past trips, which helps you find intermittent power problems that aren't present when you arrive on the service call.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eUniversal 190–600 VAC input and 50\/60 Hz operation let one stocked part cover most commercial rooftop units, chillers, pumps, and 3-phase split systems. It accepts control voltages from 18 to 240 VAC. The SPDT output is rated 10 A at 277 VAC. Common 1\/4\" quick-connect terminals give clean, secure connections without exposed wire. Load-side monitoring is optional, and the menus are available in English or Spanish.

The PLUS+ adds a real-time clock that date- and time-stamps each fault, plus a Modbus RS485 port so it can connect to a building management system.
