Tamper-proof dual thermostat
FTD 011
Fixed thermostat normally closed (NC) and normally open (NO) contacts in one casing. Unlike thermostats with changeover contacts, the double thermostat switches independently. This allows heating and cooling devices to be switched in different temperature ranges.
- Normally closed (NC, normally closed, heating) and normally open (NO, normally closed, cooling) in one casing
- Snap-action contact enables independent switching
- Fixed temperature setting
- High switching accuracy
- Clip mounting
