TAMPER-PROOF THERMOSTAT NC normally closed
FTO 011
The thermostat opens when the temperature rises. Used for regulating heaters or switching signal devices in the event that the temperature falls below the minimum limit. The temperature is pre-set, allowing for high-precision control.
- Small dimensions
- Pre-set temperature
- High-precision control
