Description
Protect your three-phase HVAC/R equipment with the ICM Controls 3VMS — a powerful all-in-one solution that combines a programmable 3-phase line voltage monitor with a high-capacity surge protection device for reliable performance in demanding environments.
Features:
- Dual Protection in One Unit: Combines the capabilities of the ICM450A voltage monitor and ICM530 surge protective device into a single compact, easy-to-install module.
- Full Voltage Monitoring: Detects over-voltage, under-voltage, phase loss, phase reversal, and phase unbalance (adjustable between 2-20%) — helps prevent motor and circuit board failures.
- High Surge Capacity: TMOV technology rated for up to 150,000 amps surge current, Type 1 & 2 protection modes (L-L, L-N) ensures equipment safety during power spikes.
- Robust Construction & Flexibility: Factory-prewired for 208/240 VAC service.
- Modular, field-replaceable components for easier maintenance and long-term usage.
- Separate 40A contactor fully disconnects loads under fault conditions.
- Built for Harsh Environments: NEMA 4X rated enclosure for outdoor/splash-prone applications.
- Backlit LCD display with fault history logging – get visibility into voltage issues over time.
- Warranty & Certification: UL listed (ICM450A: file E53944; ICM530: file E347279).
Applications:
- Ideal for residential or commercial three-phase 208/240V systems, especially HVAC/R setups where power quality matters. Great for:
- Protecting compressors, motors, and sensitive control electronics from voltage anomalies and surges
- Industrial or outdoor installations where water, dust, or harsh weather could affect conventional equipment
