Thermostat and temperature limiter (3-phase)

Thermostats designed to regulate temperature in heating devices. They allow for direct control of three-phase circuits. A built-in non-self-resetting temperature limiter protects against excessive uncontrolled temperature increase. The thermostat can be reactivated after the limiter has tripped by manually resetting the device ( by pressing the red button on the case ).
