Page 3: General Notes
2. Application Ziehl-Abegg PTC thermistor relays protect motors, transformers, machines and equipment against thermal overload. These are according to EN 60947-8 and are thus exchangeable. Used in conjunction with respective PTC thermistors they provide a reliable temperature protection in the temperature range 60 °C up to 180 °C. -

7. Detailed description A current monitors continuously the resistance of the PTC thermistors. In cold state, the resistance is ≤ 250 Ω per thermistor (thermistor circuit ≤ 1.5 kΩ). The relay has picked up and contacts 11/14 are closed. The resistance of the thermistor rises rapidly at detector operating temperature TNF. -

The manual resetting may be only possible, if all safety functions and protection device are effective. • Trip devices types U-EK230E have an interlock function. The stop instruction remains, until pressing the push-button „Reset“ a reset is made. A start-up is only possible, if no case of failure occurs and the motor is cooled down to a sufficient value of temperature. -
