Page 3: General Notes
6 PTC thermistors in series 4 Application and brief description Ziehl PTC thermistor relays protect motors, transformers, machines and equipment against thermal overload. Used in conjunction with respective PTC thermistors they provide a reliable temperature protection in the temperature range 60 °C up to 180 °C. -
Page 4: Summary Of Features
ZIEHL PTC thermistor relays are conform to EN 60947-8 and are thus exchangeable. PTC-thermistors according DIN 44081 and DIN 44082 shall be connected. PTC thermistors are suitable for the installation into windings of electrical machines, bearings and transformers as well as to monitor the temperature of liquid media, airflow and gases. -
