Star-delta starters

 

 

 


Technical characteristics:
 - Model: LT3
 - 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°÷65ºС
 - 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
