PTC Resistor Relay, Model MS220K, 2 contacts, AC 220-240V (Ordering Code T221765) HS Code: 85364900 Country of origin DE
These 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, therefore 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.
