Schneider Electric LTMR08MFM, part of the LTMR (TeSys T) sub-range, is designed for motor management with a variety of control modes including local via terminal block, local via HMI terminal, and remote via network. It supports operating modes such as overload, independent, reverser, 2-step, 2-speed, and custom mode. The part offers comprehensive fault management features like manual, automatic, and remote reset, alongside protection fault counters, protection alarm counters, diagnostic fault counters, motor control function counters, fault history, and diagnostics for internal watchdog fault, controller internal temperature, temperature sensor connection, current connection, voltage connection, and loss of communication. It records motor statistics like the number of motor control commands, operating time, number of starts per hour, last start I max, and duration of last start. Thermal overload statistics include time to trip and time to restart, while system operating statistics cover run, on, start, alarm, and fault statuses. The connection type is 3 measurement current transformers with screw-clamp terminals, and it uses the Modbus communication protocol. It is a 3 Pole device with protection functions for thermal overload, motor temperature, phase imbalance, phase failure, phase reversal, long starting time, locked rotor, minimum and maximum current load limit variation, earth fault, and frequent starting. The rated current ranges from 0.4-8 A, with a maximum of 800 A using CT. Protection settings are detailed for thermal overload, motor temperature, phase imbalance, phase failure, phase reversal, long starting time, locked rotor, current load limit variations, and earth fault. The supply voltage is AC 100-240 V, with a rated voltage for phase-to-phase of 690 V at 50-60Hz. The minimum current is 0.4 A, and the maximum is 8 A. Measurement functions include current/phase, earth current, average current, current imbalance between phases, thermal capacity level, and motor temperature rise.
