Schneider Electric Mini Thermal Overload Relays - LR2-K RangeSchneider Electrics K thermal overload relays are adjustable from 0.11 to 11.5 A, they have been predominantly designed for use in applications that require motor protection.This range of mini thermal overload relays feature compensated and phase failure sensitivity, the range also offers manual and automatic reset. Each overload relay has 3-poles and screw clamp terminals.Features & Benefits • Commonly referred to by the range short name - LR2K • Easy maintenance checks, check the tightening of cables through conducting thermographic testing and checking the mechanical operation of the product through manually operating the test, reset and stop buttons • Direct mounting under a contactor is achievable • Standards - IEC 947, BS4941, VDE 0660, NFC63-650 • Standards - CSA, UL, DEMKO, NEMKO, SEMKO, FIMKO, PTBApplications of a Contactor and Control Overload Relay • The majority of the time is to protect a motor • To detect both overload conditions and fault conditions to then announce trip command for a protective device • To deactivate a device whenever it pulls high current • Sometimes developed into microprocessor systems and solid-state electronics
