The BUI-6 unit is designed to be built into explosion-proof shells of explosion-proof hoists and complete devices and is used to control the intrinsically safe circuits by contactors, starters and other devices of low power. The control circuits of the BUI-6 are intrinsically safe with a type of explosion protection. The blocks provide protection against loss of control in the event of a break in the control circuit. Intermediate relays of the block are turned on only when the control button is pressed and turned off when it is released.
