Protects the motors against over temperature caused by excess ambient temperature, insufficient ventilation or cooling, etc.
- DIN rail mounting.
- Visual indication of trip cause.
- Controls the temperature by the use of thermistors (PTC sensors).
- Detects short-circuit (< 25Ω) and rupture in the circuit of sensors.
- Protects the motors against over temperature caused by excessive ambient temperature, insufficient ventilation or cooling, etc.
- Applicable in transformers and other machines.
