comfort actuator strawatherm 230VNo. 55-005076CBSTwo-point actuator de-energised closed for connection to room thermostats with two-point output for underfloor heating.De-energised closed versions with 230 V operating voltage.RE-OPEN function:The unique RE-OPEN function enables a recoverable manual setting "manually open".The actuator is equipped with a position indicator (automatic / open manual).It has an electrically heated, overtravel-proof expansion system.The actuating force in the closing range is adapted to thermostatic valve bodies with soft-sealing valve discs.The actuator is maintenance-free and operates silently.Application:The thermal actuator can be used for temperature and / or time-based2-point control, particularly for surface heating and cooling in homes, offices, schools, hotels, etc.Function:The position indicator in the de-energised closed (NC) version enables a simple function check,e.g. when installing the actuator on heating circuit manifolds.When the operating voltage is applied, the expansion system of the actuator is heated.After the dead time has elapsed, the uniform opening process takes place.If the voltage is interrupted, the actuator closes after the dead time has elapsed by cooling the expansion system.Technical data:- Design variant: de-energised closed (NC)- Operating voltage: 230 V (AC) + 10 %...- 10 %, 50/60 Hz- Inrush current: < 250 mA for max. 300 ms- Operating power: < 3 W- Mounting thread: M30 x 1.5- Travel: 4.0 mm- Actuating force: 100 N ± 5 %- Opening and closing time: approx. 3 min- Media temperature: 0 to 100 °C- Storage temperature: -25 to 60 °C- Ambient temperature: 0 to 50 °C- Degree of protection/protection class: IP 54 / protection class II at 230 V AC- Overvoltage resistance: acc. to EN 60730-1 min. 2.9 kV- Connection cable: 2 x 0.5 mm²- Cable length: 1 m- Installation position: all installation positions permitted- Housing material: plastic PA 66Dimensions WxHxD: 46 x 72 x 46 mm EAN: 4260435410454Item number: 6314825Brand: comfort by sanibelManufacturer: strawa Wärmetechnik GmbHPhone: 036256 8661-0Email: [email protected]Subject to technical modifications.Two-point actuator, normally closed, for connection to room thermostats with two-point output for underfloor heating systems. Normally closed versions with 230 V operating voltage. RE-OPEN function: The unique RE-OPEN function enables a recoverable manual setting "manually open". The actuator is equipped with a position indicator (automatic / open manual). It has an electrically heated, overstroke-proof expansion system. The actuating force in the closing range is adapted to thermostatic valve bodies with soft-sealing valve discs. The actuator is maintenance-free and operates silently. Application: The thermal actuator can be used for temperature and / or time-related 2-point control, especially for surface heating and cooling in homes, offices, schools, hotels, etc. Function: The position indicator in the de-energised closed (NC) version enables simple function testing, e.g. when installing the actuator on heating circuit manifolds. When the operating voltage is applied, the expansion system of the actuator is heated. After the dead time has elapsed, the uniform opening process takes place. If the voltage is interrupted, the actuator closes after the dead time has elapsed by cooling the expansion system.
