683PRESSURE CONTROLPRESSURE COMPENSATION DEVICEDATA SUBJECT TO CHANGE WITHOUT NOTICE.Technical DataHigh degree of protection (IP55) Easy to installIn a tightly closed enclosure, pressure differentials can occur during extreme temperature variations, such as day/night operation. When this occurs, the risk of dust and humidity being absorbed into the control panel increases dramatically. The specially designed pressure compensation plug DA 084 permits a controlled change in pressure and can be installed easily in any enclosure. The pressure compensation device is suitable for use in enclosures and electrical cabinets in accordance with DIN EN 62208.Mounting PG 29 thread with union nut Mounting position vertical* Material plastic, UL 94V-0 Sealing NBR gasket Air Interface Approx. 2.8 in2 (7 cm2) Operating/storage temperature -49 to 158%u00b0F (-45 to 70%u00b0C)Dimensions %u00d8 2.58%u201d x 1.2%u201d (%u00d8 65.5 x 30.5mm)* Protection type is restricted to IP54 if mounting position is not verticalInstallation A hole with a diameter of 1.46%u201d (37mm) is required for mounting. Make sure that the sealing gasket is placed on the outer side panel of the enclosure. For optimal pressure compensation, it is recommended to use two devices on opposite sides towards the top of the enclosures.Part No. Protection type 1 packing unit Weight (approx.)08400.0-02-9002 IP55 2 pieces 1.1 oz.
