Benefits
The LT6 multifunction relay incorporates multiple functions which can be configured locally or remotely, and communication via a bus and its I/ O, making it an intelligent protector, ideal for the highly demanding motor protection environment.
Applications
* Industry, infrastructure, building, etc:
- Motor protection and control
- Protection: thermal overloads, phase loss and imbalance, stalling, reversal of direction of phase rotation, no-load operation and long starting, earth leakage current, etc
3-pole multifunction relay, for thermal protection and control of motors from 0.2 to 800 A
Description
* It protects: against thermal overloads, temperature overruns ( PTC probe) , phase imbalance, earth leakage current, no-load operation, long starting, overtorque and rotor locking, etc
* It provides: fault and alarm indication via a remote display unit, motor control, etc
* Rated current:
0.2… 1 A, 1… 5 A: LT6-P0M005FM 5… 25 A: LT6-P0M025FM
> 25 A: use an LT6-CT external current transformer with 1 A or 5 A secondary current
* Communication via bus ( works with or without) :
- Protocol: Uni-Telway, Jbus/ Modbus
- receipt of configuration parameters
- exchange of data: measurements, logs, counters, etc
* On front panel: 7-segment display unit for viewing protection faults, test pushbutton, reset pushbutton, DIP switch, serial interface ( 9-pin SUB-D)
