Description
About the CM-MSE
About the CM-MSE
The ABB CM-MSE (SKU: 1SVR550801R9300) is a thermistor motor protection relay designed to safeguard electric motors from overheating by monitoring PTC thermistor signals embedded in motor windings. Featuring a single normally-open (1NO) output contact and a rated supply voltage of 220–240V AC, the CM-MSE provides reliable thermal protection in control panels and industrial automation systems. Its compact 22.5 mm width makes it ideal for DIN rail installation in space-constrained enclosures.
Certifications & Standards
- UL 508: Listed to UL standard for industrial control equipment (USA)
- cUL: Canadian UL certification for industrial control equipment
- CSA: Certified to Canadian Standards Association requirements
- CE: Compliant with European Union directives for electrical equipment
- UKCA: UK Conformity Assessed marking for Great Britain market
- CCC: China Compulsory Certification for the Chinese market
- RoHS: Compliant with EU Restriction of Hazardous Substances directive
- REACH: Compliant with EU REACH regulation on chemical substances
Applications & Use Cases
- Motor winding temperature monitoring via embedded PTC thermistors
- Thermal overload protection for AC motors in industrial drive systems
- Control panel integration for motor starters and soft starters
- Protection of pumps, fans, compressors, and conveyor drives
- Industrial automation and process control environments
Frequently Asked Questions
- What type of sensor does the CM-MSE work with?
- The CM-MSE is designed to work with PTC (Positive Temperature Coefficient) thermistors embedded in motor windings, providing accurate and responsive thermal protection.
- What is the output configuration of the CM-MSE relay?
- The CM-MSE features one normally-open (1NO) output contact, which opens when the thermistor detects an over-temperature condition, triggering a motor shutdown signal.
- Is the CM-MSE suitable for DIN rail mounting?
- Yes. At only 22.5 mm wide, the CM-MSE is designed for standard DIN rail installation and integrates easily into compact control panels.
