PTC Resistor Relays - Series MS(R)220K

The Ziehl PTC (positive temperature coefficient) resistor relays and PTC resistors are compliant to DIN 44 081 and DIN44 082 are designed to be reliable protection from thermal overloading. Together they result in a fast and affective protective system for i.e. high value plant, installations, engines and transformers.

The Ziehl range of PTC relays offer the following advantages:

  • Sensors and relays can be used in many combinations
  • Fixed response temperatures of the sensors of 60...180 Deg. C
  • Reliable monitoring of sensor line sensors
  • 1-6 PTC resistor connectable
  • Monitoring of normally closed contacts possible
  • Housings for the fast assembly standard rail or with screws 4
  • Protection against accidental contact according to VBG4, VDE 0160 part of 100

Ziehl PTC resistor relays are routine tested and meet the following standards for PTC resistor relays: VDE 0660, VDE 0160, IEC 337-1, CENELEC hp 420 i.
