Tamper-proof thermostat (NC)
FTO 011
The NC thermostat opens when the temperature rises and is used to control heaters or to switch signal transmitters when the temperature undershoots. The temperature is permanently set. This gives you a high switching accuracy.
- Small dimensions
- Fixed temperature setting
- High switching accuracy
- Clip mounting
