Hazardous Area Thermostat
REx 011 | 15 °C, 25 °C (T6)

  • For use in hazardous areas
  • High switching capacity
  • Compact Design
  • “Pre-set” temperature
  • Ready-to-use with strain relief
  • Temperature class T6

Compact, small mechanical thermostat offering a high response accuracy, small switching difference, and a very long service life (switching cycles). This thermostat of temperature class T6 (140 °F / 60 °C max.) is utilized for the regulation of heaters deployed in hazardous areas. The high switching performance allows direct control of a heater.
