Electromechanical thermostat

capillary

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
