RS 1080D
The RS 1080D contactor starters are manufactured in flameproof housings. The RS 1080D starter is a double output apparatus and provides control and power supply of one motor with maximum power of 55 kW (500 V) or 45 kW (1000 V), and simultaneous control and power supply of two motors with maximum power of 22 kW (500, 1000 V) each.
The apparatuses are equipped with safety devices protecting against: short-circuits, load asymmetry, overload, main channel low insulation resistance, short circuits, high resistance and control circuit in¬terruptions, high earthing resistance, incorrect supply voltage phase sequence (option).

Application
The contactor starters are designed for controlling and powering electrical engines of mining driver systems from three-phase supply networks with the transformer's insulated neutral point on the secondary side.
The contactor starters meet to requirements of the European Directive 94/9/EC (ATEX) for equipment in group I, category M2, and can be used in methane and coal dust exsplosion hazardous areas of underground mines.

Design
The contactor starters are made in a flameproof housing. Devices are fitted with protective devices against:
- short circuits,
- load asymmetry,
- overload,
- main channel low insulation resistance,
- short circuits, high resistance and control circuit interruptions,
- high earthing resistance
- incorrect power voltage phase sequence (optionally).
The starters can optionally be fitted with phase sequence control system which is specifically important when powering pumps as incorrect engine rotation may cause damage to the device.
