Schneider Electric LRD325L 3-pole thermal overload relays are designed to protect ac circuits and motors against overloads, phase failure, long starting times and prolonged
stalling of the motor. These overloads come in ranges from 9 AMPS up to 65 AMPS, directly mount to any LC1D40A to LC1D65A contactor and have a choice of manual or automatic reset. These overload relays are rated for Class 20, which means they trip in 20 seconds or less in an over-amperage condition.
