Explosion-proof twilight switch DVG-SVET (CCA-H-RELAY)PURPOSE AND SCOPE OF APPLICATION

Window of the explosion-proof twilight switch DVG-SVET is made from impact-resistant heat-resistant glass. Borosilicate glass contains sodium and calcium in their composition which makes them more resistant to aggressive atmospheres and to thermal impact due to low expansion coefficient. Installed twilight switch sends a command to close or open a circuit when a preset illumination tresholddefined by a photocell is reached.

Full production cycle starting from casting molds and to ready product is performed at the explosion-proof equipment plant “ZAVOD GORELTEX” Co. Ltd. on the territory of the Russian Federation.

Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) that regulates application of electrical equipment in hazardous areas, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.

Сумеречный выключатель с двумя нормами регулируемой освещенности

TWILIGHT SWITCH WITH TWO NORMS OF REGULATED ILLUMINATION

Application

Twilight switch sends a command for closing or opening of a circuit when preset illumination threshold, defined by a photocell, is reached

The relay enables contactor control, as its contacts can switch current in inductive AC circuit. Switching of switch’s contact occurs upon reaching of preset illumination threshold.
