Technical characteristics of LT4: - Rated operating current range: from 7 up 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: - Option for change of the thermal protection according to the
motor power - Metal body: covered with corrosion-proof paint - Low power
consumption and small dimensions - High reliability of the current parameters -
High efficiency and long term of operation Functions: - For direct start,
reverse start and protection of induction motors with short connected rotor - To
avoid secondary unwarranted switching on of the starter at transitory lowering
of the voltage - To protect the motor from overload in the range of the
corresponding thermal protection Applications: - Industry - Infrastructure
Mounting: To a flat surface using bolts/screws Standards: EN60947-1;
EN60947-4-1; LVD; EMC
