Product Overview
The CM-MPS 1SVR430884R1300 is a compact multifunctional three-phase monitoring relay within ABB CM control relay series. It continuously monitors three-phase mains parameters to detect critical grid abnormalities including phase loss, incorrect phase sequence, voltage unbalance, overvoltage and undervoltage conditions. Configurable DIP switches and front potentiometers allow technicians to customise voltage thresholds, unbalance limits and tripping delays to match site-specific load requirements. Two independent SPDT relay outputs provide fault signalling or direct cut-off control for upstream contactors. Electrical maintenance teams integrate this relay to safeguard costly three-phase machinery against unstable power conditions. Early detection of supply irregularities prevents motor winding burnout, compressor damage and unplanned production stoppages caused by poor three-phase power quality.
Application Scenarios
- Industrial Three-Phase Motor Control Panels: Installed upstream of large fan, pump and conveyor motors. Phase sequence protection prevents reverse rotation at commissioning, while phase loss monitoring avoids single-phasing induced motor overheating.
- HVAC Chiller & Refrigeration Compressor Systems: Guards scroll and screw compressors against voltage unbalance and supply drop-outs. Adjustable time delay eliminates nuisance tripping from brief grid voltage transients.
- Petrochemical Skid-Mounted Process Equipment: Monitors three-phase power for field-mounted pumping and mixing units. Wide operating temperature range delivers consistent monitoring performance in non-climate controlled electrical enclosures.
- Water & Wastewater Treatment Facilities: Protects multi-phase submersible pumps and aeration equipment. DIN rail form factor enables simple integration within compact MCC panels used across distributed pumping station networks.
