ELECTRIC MOTORS 155 (F)
When the limit temperature is exceeded, the sensor contacts open. When the temperature falls below the limit temperature, the contacts automatically reconnect.
The built-in switch is intended for installation in the windings of motors, transformers and coils.
High voltage resistance up to 2.0 kV eff, 50 Hz, protection class I VDE.
