Junction box BDR-25-2 Y1

Junction boxes BDR (the BDR block) is a typical product and is intended for protection of adjacent underground metal designs against electrochemical corrosion. Block BDR may have one, two, three or four channels. Every channel contain six resistors with connectors, one diode and fuse. When parallel connection of four channels, the block can be used as the polarized electro-drainage device with rated current up to 100 А (for 4 channels) with an opportunity current measure of each channel.

All multi channel modifications of the BDR have built-in switched ammeter (if it has 2, 3 or 4 channels) for control of each channel current.

Block BDR is made in the metal case with a high-quality powder covering and designed for operation in field conditions and indoor. Also this blocks may be mounted on the cathodic protection test-stations SKIP-102-2,4 by a special arm.
