Type de relais thermique PTC MSR220K2

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

The MSR220K2 monitors 2 PTC resistor sets at the same time. If a temperature rise occurs in one set, the appropriate output relay releases. With this relay, 2 PTC-sets can be independently monitored.

Part number:
T221945 AC 230 V
T221943 AC / DC 24 V
