Schneider Electric LTMR08PFM, 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 capabilities with manual, automatic, and remote reset options, alongside protection fault, alarm, diagnostic fault, and motor control function counters. It also includes fault history and diagnostics for internal watchdog faults, controller internal temperature, temperature sensor, current, and voltage connections, and motor control commands. The LTMR08PFM features a connection type of 3 measurement current transformers with screw-clamp terminals and uses the Profibus communication protocol. It is a 3 Pole device with protection functions against thermal overload, motor temperature, phase imbalance, phase failure, phase reversal, long starting time, locked rotor, minimum and maximum current load limit variations, and earth fault. It also includes a frequent starting protection mechanism. The rated current ranges from 0.4-8 A, with a maximum of 800 A using CT, and offers various protection settings 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 (AC) 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.
