- 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 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.

¹ When connecting with stranded wires, wire end ferrules must be used.
Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may change. This can lead to a voltage drop and/or self-heating of the contacts.
Convenient minimum setpoint symbol on the NC thermostat to assure enclosure temperature remains above freezing.
