Thermostat switch (NC)
KTO 111
The mechanical NC thermostat opens when the temperature rises and is used to control heaters or to switch signal transmitters when the temperature undershoots. The use of push-in terminals prevents the supply lines from coming loose.
- Fixed supply lines thanks to push-in terminals
- Time saving thanks to tool-free connection
- Large adjustment wheel enables convenient adjustablility
- Optimized air inlets
- Can be used at altitudes of up to 5000 meters

| Note | Overvoltage category: II: up to 5000 m III: up to 2000 m. The controller's contact system is exposed to the effects of the environment, which can change the contact resistance. This can lead to a voltage drop and/or self-heating of the contacts. Stripped length of rigid wire cable: 8 to 12 mm. Wire end ferrules (square or trapezoidal crimped) must be used for connections with stranded wires. Length of wire end ferrule: 8 mm or 12 mm. The height of the current has an influence on the tolerance accuracy, values specified: Switching resistive load (switching inductive load). |
