Rotor oil starters

 

Rotor oil starters consist of a step-switch with an appropriate number of starting positions and oil- immersed resistors. The step-switch contacts are designed only for starting, while the end contacts are designed for continuous load due to rated rotor current.

Features:
- for starting induction slip-ring motors of powers up to 1400 kW at full load, and 2800 kW at half load
- maximum rotor voltage up to 2000V
- maximum rotor current up to 1000A
- protection degree IP44 (on request IP54)
- normally have motor drive for remove control
- according to the standard IEC 60529.
