Detailed Description
 


thermal overload relay/thermal relay/electrical relay are devices designed for protection of induction motors from overload

LT2 Thermal Overload Relays/electrical relay

 

The thermal relays LT2-K/Exx series are devices designed for protection of induction motors from overload or overthear.They are mounted to contactors LT 1 K/Dxx series and an operating circuit for motor control is passed through their NC contacts.The operation of these devices is based on the curving of bimetal plates mounted in the themal relay caused by the current passing through them. When the current to the consumer gets higher due to failure,the thermal current gets higher which leads to additional curvig of the bimetal phates and at getting above the limit value for the plate it pushes the breaking mechanism and breaks the operating circuit.The choice of a suitable protection prevents motor;s operation at unusal temperature conditions and guarantess maximum constant operaion.increases the effectivness and prolongs the tem of exploitaton 
 
Functions
Switching off afternating current consumers at current overload
making of control systems for consumers
used as a protective operating element in control panels of induction motors
remarkable with high reliability of current characteristics
