Tamper-proof thermostat (NO)
FTS 011
The NO thermostat closes when the temperature rises and is used to control filter fans, heat exchangers, cooling devices or to switch signal transmitters when the temperature is exceeded. The temperature is permanently set. This gives you a high switching accuracy.
- Small dimensions
- Fixed temperature setting
- High switching accuracy
- Clip mounting
