Danfoss CAS thermostats are temperature-controlled switches. The position of the contacts depends on the temperature of the sensor and the set scale value. In this series, special attention has been given to meeting demands for a high level of enclosure, robust and compact construction, and resistance to shock and vibration.
The CAS series covers most outdoor as well as indoor application requirements.
CAS thermostats are suitable for use in monitoring and alarm systems in factories, diesel plant, compressors, power stations and on board ship.
