Description
- Adjustable thumbwheel setting
- Compact design
- Small hysteresis
- High switching capacity
- DIN rail mountable
The ST 011 thermostat is an SPST regulator with small hysteresis. The housing design ensures optimized air circulation around the sensor element. Thermostat NC (normally closed): Thermostat opens on temperature rise (red thumbwheel) – for regulating heaters or for switching signal devices when the temperature has fallen below the minimum value. Thermostat NO (normally open): Thermostat closes on temperature rise (blue thumbwheel) – for regulating filter fans, heat exchangers, cooling devices, or for switching signal devices when temperature limit has been exceeded.
