THERMISTOR-MOTOR PROTECTION RELAY SERIES 8510

The R. STAHL Series 8510 thermistor motor protection relay offers motor protection for all motor outputs since it detects overheating via a direct measurement of the motor winding temperature: PTC resistors measure the stator winding temperature and trigger the relay when the limit value is reached. Only after cooling down does it switch back to normal operation. Optional: The relay only switches back on again only after pressing the “RESET” button

– One device suitable for all motor outputs
– Direct measurement of temperature in the stator winding via PTC resistors:Robust modules for anti-vibration screw connection in Ex e enclosures
