Normally for overload relay setting depend on FLA (Full Load Ampere) of motor.We can see at the NAMEPLATE of motor.Normally setting for overload is 5% until 10 % more than FLA. An application for this. Choose the lower heater number if the controller is cooler than the motor. Buy LRD3365 - Schneider Electric - OVERLOAD RELAY, 80-104A. devicenet ready. Overload relays are designed to operate between 110% and 120% of the set value. A thermal overload relay works on the heat produced by the excessive overload current.The heat produced by the overload current is utilized to trip the motor circuit. Relay electrical specs include current range, trip information, phase, and control voltage. These relays can be mounted directly on the contactor or mounted separately.
