Specification
Contact cased thermostats are mainly used in applications, where the emphasis is put on visual aspect and easy control, or where it is convenient to prevent direct contact with the contacts. Main advantages of these thermostats are easy control, mounting and reliability.
Widely used for switching of boiler circulation pump. Thermostats THP, WTHP feature change-over contact for connection and disconnection of electric circuit. While using thermostat THP it is possible to set the switching difference. Type THP is also supplied in design with covered regulation dedicated for protection against unintended contact or unprofessional manipulation.
Thermostat series WTHP is due to its wider range suitable for applications, where it is necessary to regulate temperatures close to zero. For these purposes serves also the higher protection IP 40.
