MS220K and MSR220K PTC-Resistor-Relay Operating Manual

PublishTime：2022-10-31

●ZIEHL PTC-resistor relays protect motors, transformers, machines and equipment against thermal overload. With ZIEHL PTC Sensors MINIKA ® applied they offer best solutions for nominal response temperatures 60°C...180°C.
●ZIEHL PTC-resistor relays are designed for PTC-sensors according to DIN 44081 and DIN 44082. Therefor sensor and relays are 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 a effectively and reliable protection in case of
■blocking rotors, heavy starts, countercurrent operation
■undervoltage and phase failure
■increased ambient temperature and hindered cooling
