Description

The CM-MSS.13S thermistor motor protection relay provides dependable temperature monitoring and protection for motors using PTC thermistors. Operating on dual voltage (110–130 V AC and 220–240 V AC), it detects overheating and disconnects the circuit before damage occurs. Once the fault condition clears, the relay automatically resets, ensuring smooth operation and minimal downtime. Designed with a closed-circuit principle, it guarantees fail-safe protection and easy system integration. For expanded automation and protective control systems, explore our industrial automation and control solutions engineered for efficient, reliable motor management.
