Product Overview
The Telemecanique LT3-SA00M Thermistor Protection Relay, part number 068822, is an electronic motor protection device designed to monitor temperature using compatible PTC thermistor probes installed in motor windings.
When the thermistor circuit detects an excessive motor temperature or a probe-circuit fault, the relay changes its output state to help protect the motor and associated equipment. The unit features automatic reset and front-panel voltage and fault indication.
Part of the TeSys LT3 series from Telemecanique / Schneider Electric, this relay is designed for industrial motor protection and control applications.
