PublishTime：2022-10-31

●ZIEHL PTC-resistor relays protect motors, transformers, machines and equipment against thermal overload. In combination with ZIEHL PTC Sensors MINIKA ® they offer best possible protection against thermal overload.
●ZIEHL PTC-resistor relays are designed for PTC-sensors according to DIN 44081 and DIN 44082. These are according to DIN VDE 0660 chapter 303 and are thus exchangeable. PTC-resistor sensors 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.
●Used in conjunction, they provide an effective and reliable protection in case of
■ blocking rotors, heavy starts, countercurrent operation
■ undervoltage and phase failure
■ increased ambient temperature and hindered cooling
