Explosion-proof control station SUV-USR
The station is designed to control the start and stop, as well as protection against short circuit currents and overload of three-phase asynchronous electric motors with a squirrel-cage rotor, powered by an alternating current network with an isolated neutral, in mines and mines that are dangerous for gas (methane) and dust. It is used as part of an ore storage complex.
The delivery set includes a control panel PU-USR ESHUL.21.06.00.00.000.
