CM-MPS.41S ABB PTC Motor Protection Relay Auto Reset 24VAC with 1NO Contact
The ABB CM-MPS.41S is a high-performance PTC motor protection relay designed to safeguard electric motors against overheating and thermal damage. This relay monitors PTC thermistor sensors embedded in motor windings, providing reliable protection for industrial motor applications.
Featuring automatic reset functionality, the CM-MPS.41S automatically restores normal operation once motor temperature returns to safe levels, minimizing production downtime. The relay operates on 24V AC control voltage and provides 1 normally open (NO) contact for integration with control systems and alarm circuits.
Compatible with standard PTC thermistor sensors (typically 1–3 sensors per motor), this relay detects abnormal temperature increases and triggers protective actions before critical damage occurs. The compact design allows for easy DIN rail mounting in control panels, while the LED status indicator provides visual monitoring of relay operation.
