PTC thermal relay type MS220K

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

Part number:

T22174 AC 220-240 V 1 contact
T221741 24 V AC / DC 1 contact
T221765 AC 220-240 V 2 contacts
T221761 24 V AC / DC 2 contacts



Functional overview

  • 1 PTC-resistor set with up to 6 PTC-sensors (250Ω) in series
  • output relay with 1 or 2 change-over contact (co)
  • operating status display with LED
  • K-Housing, vertical terminal order
  • width 22.7 mm
  • snap mounting on 35 mm standard DIN rail or screw mounting
