Explosion-proof bimetallic thermostats THERMODACHIK-1
Product Description
The explosion-proof bimetallic thermostat THERMODACTOR-1 is used to collect information and monitor the external temperature of heating systems, regulate the internal temperature of heated instrument cabinets, distribution cabinets and control cabinets, as well as to monitor temperature changes above or below a specified range or as an emergency circuit contact in an explosion-hazardous area.
It comes with two types of contacts: NO or NC. If the temperature drops below the permissible limit, the thermostat contact closes (or opens, depending on the version) automatically. The explosion-proof thermostat directly controls loads up to 10A. Switching on higher values or three-phase circuits is accomplished via a contactor.
