LTMR full from , What is LTMR Industrial MCC Penal DOL Star Delta starter

LTMR full from - Low Tension Motor Relay

What is LTMR?

Schneider TeSys T Motor management system

Two hardware components

1 ) LTMR - Main controller

2) LTME - Expansion & Voltage sensing (voltage range 110V - 690V AC)

Application: DOL ,STAR-DELTA, R-DOL AUTO TRANSFORMER,  MOTOR STARTER.

• The microprocessor-based LTMR controller is the central component in the system that manages the control, protection, and monitoring functions of single-phase or three-phase AC induction motors.

LTMR FUNCTION

1) Motor Metering and Monitoring

2) Motor Protection

3) Motor Control

1) Motor Metering and Monitoring

✓ Easily Measurement - Motor Current, Voltage, Frequency, Power, Power Factor

✓ Monitoring 

• Fault and warning counters.
• Motor history.
• System and device monitoring faults.
• System operating status.

2)Motor Protection

• Thermal motor protection with time delay
• Current motor protection with time delay
• Voltage and power motor protection with time delay

3) Motor Control

Control channels (local/remote control source selection),Operating modes, Fault management independently start, stop input
