Thermal protection relay for series LT3 S motors

Protection relay with probe, LT3 series, that permanently controls the temperature of machines that require protection (motors, alternators etc..). Operates via CTP thermistor probes.
Automatic or manual reset.
Faults displayed on the front panel of the device or remotely, except for version LT3 SE, which does not have this function.
Fault detection if the probe circuit is accidentally cut off
Three versions are available:
LT3 SE: Control devices with no fault memory.
LT3 SA: Automatic reset with thermistor short circuit detection device.
Warning light on front panel.
LT3 SM: Device with manual reset and thermistor short circuit detection.
On the front panel there is a fault warning light and voltage indicator, and a test and reset button.
