CAPILLARY
THERMOSTAT
Type RAC
Three-phase electromechanical temperature controller (TR) or temperature limiter (TW) in combination with a safety temperature limiter (STB). For temperatures up to 350 °C. The reset of the STB after action has to be done manually. Contrary to the TR / TW, 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 combi controller is calibrated for an ambient temperature of 23 °C at the switching head and capillary tube.
Applications:
- Hot water storage
- Auxiliary heating for solar systems or heat pumps
- And other applications with the requirement for a temperature-dependent corresponding switching
Characteristics:
- switching cycles at nominal load TR/TW up to 100.000; STB up to 500
- Certified by EN 60730-1/2-9
- Three pole, switch off, 24…400V AC (20A)
- Switch off temp up to 350 °C
- Calibrated for ambient temperature 23 °C
- Capillary tube and sensor in copper or stainless steel
- Capillary tube length from 300 mm to 3500 mm
- Protective tube for capillary, length by choice
- Sensor in different diameters and profiles
- TR/TW – operation type 1.B approved by EN 60730-1/2-9
- STB – operation type 2.B.H.K.L approved by EN 60730-1/2-9
- RoHS-Complaint
