TeSys LT3 thermistor protection relays monitor the temperature of machines via PTC thermistor probes to prevent over-heating.
- LT3-SE: with automatic reset
- LT3-SA: with automatic reset; voltage fault indicator light incorporated
- LT3-SM: with manual reset; voltage fault indicator light, device “test" and "reset" button incorporated
TeSys LT3 is a slim relay with built-in machine temperature control function, quick and simple selection.
- Provide additional motor protections compared to standard overload relay
- Multiple control voltages available
- Wide band version from 24 to 230 V for LT3SA and LT3SM versions
Suitable for a variety of applications in industry, infrastructure and building, including:
- General protection and protection of motors with PTC probes
- Protection of resistors, bearings, capacitors
- Motors with frequent starts or operating in severe environments
