- Rated operating current range: to 93А АС
- Rated voltage of the controlling voltage: 400V АС; 50/60Hz
- Rated operating voltage: 690V
- Insulation voltage: >690V
- Surge voltage wear resistance: 6 000V
- Option for change of the power supply operating voltage
- IP code: IP54
- Ambient temperature : -10 �÷65 �С
- Maximum altitude: up to 2000m

Mounting: to a flat surface using bolts/screws

Advantages:
- Low power consumption and small dimensions
- High reliability of the current parameters
- High efficiency and long term of operation
- The metal body is covered with corrosion-proof paint
- Possibility for operation at higher frequency

Functions:
-Switching on/off alternating current three phase motors operating according to a scheme “star - delta”
-Does not allow secondary unwarranted switching on of the starter at transitory lowering of the voltage
- Protects the motor from overload in the range of the corresponding thermal protection
- Indication of the operating condition through a valve indicator
- Possibility for mounting of additional contacts (for the open type)

Applications:
- Industry
- Infrastructure.
