🏭 Industrial Applications

Motor Protection Systems: Safeguard three-phase motors in pumps, compressors, and conveyors from overload conditions, phase loss, and locked rotor scenarios in manufacturing facilities.

Generator Monitoring: Protect standby and prime power generators from overcurrent faults, ensuring reliable backup power for data centers, hospitals, and critical infrastructure.

Distribution Panel Safety: Monitor feeder circuits and branch loads in electrical distribution systems, preventing equipment damage and reducing fire hazards in commercial buildings.

✨ Advanced Features

• 🎯 Dual Threshold Control: Independent overcurrent and undercurrent setpoints with hysteresis adjustment
• ⏱️ Time Delay Protection: Prevents nuisance tripping during motor startup and transient conditions
• 🔔 Pre-Alarm Function: Early warning output at 80% threshold for predictive maintenance
• 🔒 Fail-Safe Design: De-energize-to-trip configuration ensures protection during power loss
• 📊 Wide Current Range: Single device covers fractional to 100A loads without external CTs

💼 System Integration Benefits

The CMW112 integrates seamlessly with SCADA systems, PLCs, and building management platforms via dry contact outputs. Its compact DIN-rail form factor fits standard control panels alongside circuit breakers and contactors. The relay's universal power input eliminates the need for separate power supplies, simplifying installation and reducing panel space requirements.

🛠️ Configuration & Setup

Front-accessible potentiometers enable quick field adjustment of current thresholds and time delays without tools. Clear LED status indicators provide instant visual confirmation of operating mode, alarm conditions, and relay states. The device supports both normally energized and de-energized operating modes to match diverse safety architectures.
