Capillary
thermostat
Type RAS
Three-phase electromechanical safety temperature limiter (STB). For temperatures up to 350 °C. The reset of the STB after action has to be done manually. The STB is self-safety, that means a capillary tube break or a leak in the sensor system will cause the contacts to open. The limiter is calibrated for an ambient temperature of 23 °C at the switching head and capillary tube.
Applications:
- Auxiliary heating for solar systems or heat pumps
- Hot water storage
- And other applications with the requirement for a temperature-dependent corresponding switching
Characteristics:
- switching cycles at nominal load up to 500
- Certified by EN 60730-1/2-9
