Switchgear type
RZS-05/PSS/3S

The switchgear (with the soft starter) type RZS-05/PSS/3S is an electrical device designed for use in underground mining in working pits in non-explosive hazard conditions and on the ground in non-explosive hazard conditions. The switchgear (with soft starter) type RZS-05/PSS/3S is designed to connect and switching on receivers in 3-phase mine grid with insulated star point of the transformer (IT system) for the rated grid voltage 500V. The soft starter built-in the switchgear provides for soft-start of any mining machine (a pump, fan, belt, etc.), and after started-up it is bridged through the bypass contactor. The switchgear type RZS-05/PSS/3S can also work without the participation of the soft starter, then a motor is started directly.
