PTC-Resistor-Relay Type MS220K2 AC 230V

Manufacturer:

Ziehl

PTC-resistor relay, single PTC-circuit

67 CAD
+ -
Products specifications
Brand ZIEHL
Country of origin Germany
Rated supply voltage ± 10/-15 %, DC +25/-20%, < 1 W , < 2 VA,
Protection housing IP 30
Protection terminals IP 20
Connectable PTC resistors 1...6 PTC according DIN VDE V 0898-1-401 (formerly DIN 44081/82)
Switching point < 4000 Ω
Attachment on 35 mm DIN rail according to EN 60 715 or screws M4
Ambient temperature range -20...+55 °C

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 MS220K2 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.
