Quick guide PTC-Thermistor-Relay MSR220K
1 Application and short description
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, counter current operation
• undervoltage and phase failure
• increased ambient temperature and hindered cooling
