Explosion-proof bimetallic thermostats DVG-TERMOSTAT1
Product Description
Bimetallic thermostats DVG-TERMOSTAT1 are designed to collect information and control the external temperature of heating systems, and regulate the internal temperature of heated instrument cabinets at explosive facilities.
Strengths
- Suitable for controlling both heating and cooling systems;
- Possibility of manufacturing based on housings of other sizes;
- Controls loads up to 10A directly;
- Switching on higher values or 3-phase circuits is accomplished through a contactor;
- Possibility of installing up to 3 cable entries.
