Technical characteristics of LT3: - Rated operating current range: to 93A A? -
Rated voltage of the controlling voltage: 400V A?;50/60Hz - Rated operating
voltage: 690V - Insulation voltage: >690V - Surge voltage wear resistance:
?6000V - Option for change of the power supply operating voltage - IP code: IP54
- Ambient temperature : -10° to 65ş? - Maximum altitude: up to 2000m 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 Mounting: To a flat surface using
bolts/screws Standard: EN60947-1; EN60947-4-1; LVD; EMC
