SCHNEIDER LTMR100EFM Series Motor Management Controller

Description

SCHNEIDER LTMR100EFM Series Motor Management Controller

The Schneider Electric LTMR100EFM is a high-performance controller part of the TeSys T smart motor management system. It is designed to provide advanced protection, monitoring, and control for single-phase and three-phase AC motors.

## Product Overview

The LTMR100EFM is a Motor Management Controller that integrates multiple functions into a single unit: protection, measurement, and communication. The “EFM” suffix specifically indicates that this model supports Ethernet TCP/IP communication protocols (Modbus TCP and EtherNet/IP).

### Key Technical Specifications

## Product Advantages

• Comprehensive Protection: Protects against thermal overload, phase failure, phase imbalance, locked rotor, and earth leakage.

• Reduced Downtime: Features predictive maintenance capabilities by monitoring motor health and historical fault data.

• Seamless Integration: The built-in Ethernet port allows easy connection to PLCs, SCADA, and IoT platforms (EcoStruxure).

• Space Saving: Consolidates many components (overload relay, current transformer, communication module) into one compact device.

• Flexibility: Can be expanded with the LTME extension module to add voltage and power measurement.

## Product Applications

The LTMR100EFM is ideal for critical processes where motor reliability is essential:

1. Water & Wastewater: Pumping stations and treatment plants.

2. Oil & Gas: Refineries, pipelines, and extraction sites.

3. Mining & Minerals: Conveyor belts, crushers, and grinders.

4. Food & Beverage: Mixers, bottling lines, and industrial ovens.

5. HVAC: Large-scale fan and compressor control in commercial buildings.

## Important Precautions (Usage Notes)

• Current Range Scaling: While the unit handles up to 100A directly, for motors exceeding 100A, external Current Transformers (CTs) must be used.

• Firmware Updates: Ensure the firmware is compatible with your PLC library/profile to avoid communication drops.

• Wiring Integrity: Tighten all terminals to the specified torque to prevent overheating or signal interference.

• Environmental Limits: Ensure the operating temperature stays within $-20^\circ\text{C}$ to $+60^\circ\text{C}$ to maintain accuracy and longevity.
